Michal Schwartz (born 1 January 1950) is a professor of neuroimmunology at the Weizmann Institute of Science. She is active in the field of neurodegenerative diseases, particularly utilizing the immune system to help the brain fight terminal neurodegenerative brain diseases, such as Alzheimer's disease and dementia. [3] [1]

Contents

Schwartz's studies have shown that the immune system supports a healthy brain's function and is vital for healing and protecting the brain in case of injury or disease.[ citation needed ]

Schwartz coined the term protective autoimmunity [4] and discovered roles for immune cells in repair and neurogenesis. She has been the elected chair of the International Society of Neuroimmunology (ISNI) since 2016. [5]

In 2023 Schwartz received the honorary Israel Prize for Life Sciences.

Education

Schwartz gained her Bachelor of Science in chemistry at the Hebrew University of Jerusalem in 1972. She received her Ph.D in Immunology in 1977 at the Weizmann Institute of Science, where she would later spend the majority of her career. She also spent time at the University of Michigan, Ann Arbor, researching nerve regeneration.[ when? ]

Career and research

At the Weizmann Institute, she progressed from senior scientist in the Department of Neurobiology to a full professor in 1998, and was then awarded the Maurice and Ilse Katz Professorial Chair in Neuroimmunology in 2016. [6] Schwartz's work in neuroimmunology has encompassed a wide range of pathologies in the central nervous system (CNS) including injury, neurodegeneration, mental dysfunction, and aging. She coined the term protective autoimmunity and demonstrated the role of immune cells such as macrophages and T cells in spinal cord repair. She also identified specific brain areas for 'cross talk' between the CNS and the immune system. This cross-talk is important for recruiting immune cells and maintaining a healthy brain, and the disruption of this cross-talk can play a role in brain aging and neurodegenerative disease. She also showed this role in pregnancy and fetal brain development, where immune disruption in the mother can be linked to neurodevelopmental disorders in their children. Another focus of her work has been on repurposing cancer immunotherapies such as PD-1 blockers to treat neurodegenerative disorders such as Alzheimer's disease.

Macrophages

The Schwartz team discovered that bone marrow-derived macrophages are needed for central nervous system (CNS) repair. The brain-resident myeloid cells (the microglia), and infiltrating monocyte-derived macrophages are not redundant populations, despite their myeloid phenotype, and display distinct functions in resolution of brain inflammation. [7] [8] [9]

Autoimmunity

In her research, Schwartz discovered that the ability to cope with sterile CNS injuries requires support in the form of an adaptive immune response mediated by CD4+ T cells that recognize CNS antigens. She coined the concept of protective autoimmunity, to distinguish this response from autoimmune disease, in which the anti-self response escapes control. Over the years, it became clear that adaptive immunity is needed to facilitate the recruitment of immunoregulatory cells, including bone marrow-derived macrophages and FoxP3 regulatory T cells, though the balance between regulatory T cells and effector memory cells is different in the periphery versus the brain. [10] [11] [12]

Brain Homeostasis

Schwartz’s team discovered the role of adaptive systemic immune cells, and specifically T cells recognizing brain antigens (Protective autoimmune T cells), in supporting the cognitive capacity of the healthy brain, for lifelong neurogenesis, and functional brain plasticity. These observations paved the way for numerous additional discoveries in which the brain-immune axis was described. [13] [14] [15]

The Choroid Plexus

Schwartz’s team identified the brain’s choroid plexus (CP) within the blood-cerebrospinal fluid barrier as an immunological interface between the brain and the immune system. It serves as a niche that hosts immune cells, and as a physiological entry gate for leukocytes. Focusing on this unique niche within the brain led the Schwartz group to propose that IFN-γ holds the key to regulating CP gateway activity. Her team further showed that in brain aging and neurodegenerative diseases (studied using both mouse models and human samples), dysfunction of this interface is determined both by signals originating in the brain, and signals from the aged immune system, which led to the identification of Type-I Interferon (IFN-I) at the CP as a negative player, affecting the fate of the aging brain in general, and of microglia, in particular. A similar IFN-I signature at the CP was subsequently discovered by others in Alzheimer’s disease and in the postmortem brains of infected patients who died from COVID-19. [16] [13] [9]

Immunotherapy

The discovery that adaptive immunity plays a key role in brain function and repair, the need for bone marrow-derived macrophages to resolve local brain inflammation, the fact that Alzheimer's disease (AD) and all forms of dementia are mainly age-related diseases, and the fact that the immune system is particularly affected by aging all led Schwartz to propose a new treatment for combating dementias. Schwartz suggested empowering systemic immunity, using a form of immunotherapy by modestly blocking the inhibitory immune checkpoint PD1/PD-L1 pathway.[ citation needed ] This treatment drives an immune-dependent cascade of events, that allows the harnessing of bone marrow-derived macrophages and regulatory T cells to help clear toxic factors from the diseased brain, and to arrest the local inflammation, thereby providing a comprehensive multi-factorial therapy through modification of multiple elements that go awry in AD. Schwartz’s patents for developing such immunotherapy for AD are licensed to a small Biopharma company, Immunobrain Checkpoint. The company is awaiting a clinical trial in AD patients, supported in part by the National Institute of Aging, the US National Institutes of Health, and The Alzheimer's Association.

Students

Schwartz has mentored approximately 40 Ph.D. students [ citation needed ], [23] [8] and approximately 39 MSc students.[ citation needed ] [24] [25] Her former Ph.D students include Jonathan Kipnis, [15] Noga Ron Harel, Jasmin Fisher, [2] Asya Rolls.[ citation needed ] [24] [25] [8]

The stromal cell-derived factor 1 (SDF-1), also known as C-X-C motif chemokine 12 (CXCL12), is a chemokine protein that in humans is encoded by the CXCL12 gene on chromosome 10. It is ubiquitously expressed in many tissues and cell types. Stromal cell-derived factors 1-alpha and 1-beta are small cytokines that belong to the chemokine family, members of which activate leukocytes and are often induced by proinflammatory stimuli such as lipopolysaccharide, TNF, or IL1. The chemokines are characterized by the presence of 4 conserved cysteines that form 2 disulfide bonds. They can be classified into 2 subfamilies. In the CC subfamily, the cysteine residues are adjacent to each other. In the CXC subfamily, they are separated by an intervening amino acid. The SDF1 proteins belong to the latter group. CXCL12 signaling has been observed in several cancers. The CXCL12 gene also contains one of 27 SNPs associated with increased risk of coronary artery disease.

<span class="mw-page-title-main">Microglia</span> Glial cell located throughout the brain and spinal cord

Microglia are a type of neuroglia located throughout the brain and spinal cord. Microglia account for about 10-15% of cells found within the brain. As the resident macrophage cells, they act as the first and main form of active immune defense in the central nervous system (CNS). Microglia originate in the yolk sac under a tightly regulated molecular process. These cells are distributed in large non-overlapping regions throughout the CNS. Microglia are key cells in overall brain maintenance—they are constantly scavenging the CNS for plaques, damaged or unnecessary neurons and synapses, and infectious agents. Since these processes must be efficient to prevent potentially fatal damage, microglia are extremely sensitive to even small pathological changes in the CNS. This sensitivity is achieved in part by the presence of unique potassium channels that respond to even small changes in extracellular potassium. Recent evidence shows that microglia are also key players in the sustainment of normal brain functions under healthy conditions. Microglia also constantly monitor neuronal functions through direct somatic contacts and exert neuroprotective effects when needed.

Neuroimmunology is a field combining neuroscience, the study of the nervous system, and immunology, the study of the immune system. Neuroimmunologists seek to better understand the interactions of these two complex systems during development, homeostasis, and response to injuries. A long-term goal of this rapidly developing research area is to further develop our understanding of the pathology of certain neurological diseases, some of which have no clear etiology. In doing so, neuroimmunology contributes to development of new pharmacological treatments for several neurological conditions. Many types of interactions involve both the nervous and immune systems including the physiological functioning of the two systems in health and disease, malfunction of either and or both systems that leads to disorders, and the physical, chemical, and environmental stressors that affect the two systems on a daily basis.

<span class="mw-page-title-main">Neuroimmune system</span>

The neuroimmune system is a system of structures and processes involving the biochemical and electrophysiological interactions between the nervous system and immune system which protect neurons from pathogens. It serves to protect neurons against disease by maintaining selectively permeable barriers, mediating neuroinflammation and wound healing in damaged neurons, and mobilizing host defenses against pathogens.

<span class="mw-page-title-main">Neurodegenerative disease</span> Central nervous system disease

A neurodegenerative disease is caused by the progressive loss of structure or function of neurons, in the process known as neurodegeneration. Such neuronal damage may ultimately involve cell death. Neurodegenerative diseases include amyotrophic lateral sclerosis, multiple sclerosis, Parkinson's disease, Alzheimer's disease, Huntington's disease, multiple system atrophy, tauopathies, and prion diseases. Neurodegeneration can be found in the brain at many different levels of neuronal circuitry, ranging from molecular to systemic. Because there is no known way to reverse the progressive degeneration of neurons, these diseases are considered to be incurable; however research has shown that the two major contributing factors to neurodegeneration are oxidative stress and inflammation. Biomedical research has revealed many similarities between these diseases at the subcellular level, including atypical protein assemblies and induced cell death. These similarities suggest that therapeutic advances against one neurodegenerative disease might ameliorate other diseases as well.

<span class="mw-page-title-main">Monoclonal antibody therapy</span> Form of immunotherapy

Monoclonal antibodies (mAbs) have varied therapeutic uses. It is possible to create a mAb that binds specifically to almost any extracellular target, such as cell surface proteins and cytokines. They can be used to render their target ineffective, to induce a specific cell signal, to cause the immune system to attack specific cells, or to bring a drug to a specific cell type.

<span class="mw-page-title-main">Programmed cell death protein 1</span> Mammalian protein found in humans

Programmed cell death protein 1(PD-1),. PD-1 is a protein encoded in humans by the PDCD1 gene. PD-1 is a cell surface receptor on T cells and B cells that has a role in regulating the immune system's response to the cells of the human body by down-regulating the immune system and promoting self-tolerance by suppressing T cell inflammatory activity. This prevents autoimmune diseases, but it can also prevent the immune system from killing cancer cells.

<span class="mw-page-title-main">TREM2</span> Protein-coding gene in the species Homo sapiens

Triggering receptor expressed on myeloid cells 2(TREM2) is a protein that in humans is encoded by the TREM2 gene. TREM2 is expressed on macrophages, immature monocyte-derived dendritic cells, osteoclasts, and microglia, which are immune cells in the central nervous system. In the liver, TREM2 is expressed by several cell types, including macrophages, that respond to injury. In the intestine, TREM2 is expressed by myeloid-derived dendritic cells and macrophage. TREM2 is overexpressed in many tumor types and has anti-inflammatory activities. It might therefore be a good therapeutic target.

Protective autoimmunity is a condition in which cells of the adaptive immune system contribute to maintenance of the functional integrity of a tissue, or facilitate its repair following an insult. The term ‘protective autoimmunity’ was coined by Prof. Michal Schwartz of the Weizmann Institute of Science (Israel), whose pioneering studies were the first to demonstrate that autoimmune T lymphocytes can have a beneficial role in repair, following an injury to the central nervous system (CNS). Most of the studies on the phenomenon of protective autoimmunity were conducted in experimental settings of various CNS pathologies and thus reside within the scientific discipline of neuroimmunology.

Neuroinflammation is inflammation of the nervous tissue. It may be initiated in response to a variety of cues, including infection, traumatic brain injury, toxic metabolites, or autoimmunity. In the central nervous system (CNS), including the brain and spinal cord, microglia are the resident innate immune cells that are activated in response to these cues. The CNS is typically an immunologically privileged site because peripheral immune cells are generally blocked by the blood–brain barrier (BBB), a specialized structure composed of astrocytes and endothelial cells. However, circulating peripheral immune cells may surpass a compromised BBB and encounter neurons and glial cells expressing major histocompatibility complex molecules, perpetuating the immune response. Although the response is initiated to protect the central nervous system from the infectious agent, the effect may be toxic and widespread inflammation as well as further migration of leukocytes through the blood–brain barrier may occur.

The meningeal lymphatic vessels are a network of conventional lymphatic vessels located parallel to the dural venous sinuses and middle meningeal arteries of the mammalian central nervous system (CNS). As a part of the lymphatic system, the meningeal lymphatics are responsible for draining immune cells, small molecules, and excess fluid from the CNS into the deep cervical lymph nodes. Cerebrospinal fluid, and interstitial fluid are exchanged, and drained by the meningeal lymphatic vessels.

<span class="mw-page-title-main">Pathophysiology of Parkinson's disease</span> Medical condition

The pathophysiology of Parkinson's disease is death of dopaminergic neurons as a result of changes in biological activity in the brain with respect to Parkinson's disease (PD). There are several proposed mechanisms for neuronal death in PD; however, not all of them are well understood. Five proposed major mechanisms for neuronal death in Parkinson's Disease include protein aggregation in Lewy bodies, disruption of autophagy, changes in cell metabolism or mitochondrial function, neuroinflammation, and blood–brain barrier (BBB) breakdown resulting in vascular leakiness.
