After discovering and describing keratinocyte cytokines in late 1980s/early 1990s, he has spent the past two decades years focusing on skin homing T cells, from reporting the molecular structure of Cutaneous Lymphocyte Antigen [6] to co-discovering that non-inflamed skin contained large numbers of memory T cells. [7] A subset of these are now known as “tissue resident memory T cells” or TRM, and he demonstrated that these T cells 1) can be generated by skin vaccination, [8] 2) provide immune protection in the absence of circulating T cells, [9] 3) have a diverse T cell repertoire mirrored by circulating memory T cells, [10] and 4) utilize unique metabolic strategies to survive in the periphery, [11] and represent a prognostic factor in melanoma. [12] [13] In the diagnosis and treatment of Cutaneous T Cell Lymphoma, which he defined as a malignancy of skin resident and circulating T cells. [14] This observation has led to mechanism-based therapies, [1] more precise diagnosis [15] and prognosis. [16] Over the years this work has been supported by a MERIT award from the NIAID, a Transformative R01 Award from the Office of the NIH Director, and multiple R01's from the NIAID, NIAMS, and NCI.

Skin cancers are cancers that arise from the skin. They are due to the development of abnormal cells that have the ability to invade or spread to other parts of the body. Skin cancer is the most commonly diagnosed form of cancer in humans. There are three main types of skin cancers: basal-cell skin cancer (BCC), squamous-cell skin cancer (SCC) and melanoma. The first two, along with a number of less common skin cancers, are known as nonmelanoma skin cancer (NMSC). Basal-cell cancer grows slowly and can damage the tissue around it but is unlikely to spread to distant areas or result in death. It often appears as a painless raised area of skin that may be shiny with small blood vessels running over it or may present as a raised area with an ulcer. Squamous-cell skin cancer is more likely to spread. It usually presents as a hard lump with a scaly top but may also form an ulcer. Melanomas are the most aggressive. Signs include a mole that has changed in size, shape, color, has irregular edges, has more than one color, is itchy or bleeds.
Cutaneous squamous-cell carcinoma (cSCC), or squamous-cell carcinoma of the skin, also known as squamous-cell skin cancer, is, with basal-cell carcinoma and melanoma, one of the three principal types of skin cancer. cSCC typically presents as a hard lump with a scaly top layer, but it may instead form an ulcer. Onset often occurs over a period of months. Cutaneous squamous-cell carcinoma is more likely to spread to distant areas than basal cell cancer. When confined to the outermost layer of the skin, a pre-invasive, or in situ, form of cSCC is known as Bowen's disease.
Acral lentiginous melanoma is an aggressive type of skin cancer. Melanoma is a group of serious skin cancers that arise from pigment cells (melanocytes); acral lentiginous melanoma is a kind of lentiginous skin melanoma. Acral lentiginous melanoma is the most common subtype in people with darker skins and is rare in people with lighter skin types. It is not caused by exposure to sunlight or UV radiation, and wearing sunscreen does not protect against it. Acral lentiginous melanoma is commonly found on the palms, soles, under the nails, and in the oral mucosa. It occurs on non-hair-bearing surfaces of the body, which have not necessarily been exposed to sunlight. It is also found on mucous membranes.
Alopecia universalis(AU), also known as alopecia areata universalis, is a medical condition involving the loss of all body hair, including eyebrows, eyelashes, chest hair, armpit hair, and pubic hair. It is the most severe form of alopecia areata. People with the disease are usually healthy and have no other symptoms and a normal life expectancy.
Merkel-cell carcinoma (MCC) is a rare and aggressive skin cancer occurring in about three people per million members of the population. It is also known as cutaneous APUDoma, primary neuroendocrine carcinoma of the skin, primary small cell carcinoma of the skin, and trabecular carcinoma of the skin. Factors involved in the development of MCC include the Merkel cell polyomavirus, a weakened immune system, and exposure to ultraviolet radiation. Merkel-cell carcinoma usually arises on the head, neck, and extremities, as well as in the perianal region and on the eyelid. It is more common in people over sixty years old, Caucasian people, and males. MCC is less common in children.
Dermatoscopy also known as dermoscopy or epiluminescence microscopy, is the examination of skin lesions with a dermatoscope. It is a tool similar to a camera to allow for inspection of skin lesions unobstructed by skin surface reflections. The dermatoscope consists of a magnifier, a light source, a transparent plate and sometimes a liquid medium between the instrument and the skin. The dermatoscope is often handheld, although there are stationary cameras allowing the capture of whole body images in a single shot. When the images or video clips are digitally captured or processed, the instrument can be referred to as a digital epiluminescence dermatoscope. The image is then analyzed automatically and given a score indicating how dangerous it is. This technique is useful to dermatologists and skin cancer practitioners in distinguishing benign from malignant (cancerous) lesions, especially in the diagnosis of melanoma.
Memory T cells are a subset of T lymphocytes that might have some of the same functions as memory B cells. Their lineage is unclear.
Psychodermatology is the treatment of skin disorders using psychological and psychiatric techniques by addressing the interaction between mind and skin. Though historically there has not been strong scientific support for its practice, there is increasing evidence that behavioral treatments may be effective in the management of chronic skin disorders.
Amelanotic melanoma is a type of skin cancer in which the cells do not make any melanin. They can be pink, red, purple or of normal skin color, and are therefore difficult to diagnose correctly. They can occur anywhere on the body, just as a typical melanoma can.
Tumor-infiltrating lymphocytes (TIL) are white blood cells that have left the bloodstream and migrated towards a tumor. They include T cells and B cells and are part of the larger category of ‘tumor-infiltrating immune cells’ which consist of both mononuclear and polymorphonuclear immune cells, in variable proportions. Their abundance varies with tumor type and stage and in some cases relates to disease prognosis.

Resiquimod (R-848) is a drug that acts as an immune response modifier, and has antiviral and antitumour activity. It is used as a topical gel in the treatment of skin lesions such as those caused by the herpes simplex virus and cutaneous T cell lymphoma, and as an adjuvant to increase the effectiveness of vaccines. In an animal disease model, systemic administration of resiquimod-loaded nanoparticles has been shown to improve response rates to cancer immunotherapy with a checkpoint inhibitor through stimulation of tumor-associated macrophages. It has several mechanisms of action, being both an agonist for toll-like receptor 7 and 8, and an upregulator of the opioid growth factor receptor. On 28 April 2016, orphan designation (EU/3/16/1653) was granted by the European Commission to Galderma R&D, France for resiquimod to be used in the treatment of cutaneous T-cell lymphoma.
Mucosal melanoma is a rare condition characterized by a melanoma of the mucous membranes. This subtype is associated a worse prognosis than those arising from the skin. Mucosal melanomas occur in the head and neck (55%), anorectal (24%) and vulvovaginal region (18%), and in the urinary tract (3%). Based on the histopathologic and clinical features, melanomas of the vulva and vagina are often considered a separate disease entity. The prognosis of vulvovaginal melanomas is poor, especially for vaginal melanomas and has not improved over the last decades. While chemotherapy has not shown capacity to improve survival in clinical and observational studies, immune checkpoint inhibitors have been tested in mucosal melanomas and have shown promising response rates.
In cell biology, Meiomitosis is an aberrant cellular division pathway that combines normal mitosis pathways with ectopically expressed meiotic machinery resulting in genomic instability.
Skin immunity is a property of skin that allows it to resist infections from pathogens. In addition to providing a passive physical barrier against infection, the skin also contains elements of the innate and adaptive immune systems which allows it to actively fight infections. Hence the skin provides defense in depth against infection.
Tissue-resident memory T cells or TRM cells represent a subset of a long-lived memory T cells that occupies epithelial, mucosal and other tissues without recirculating. TRM cells are transcriptionally, phenotypically and functionally distinct from central memory (TCM) and effector memory (TEM) T cells which recirculate between blood, the T cell zones of secondary lymphoid organ, lymph and nonlymphoid tissues. Moreover, TRM cells themself represent a diverse populations because of the specializations for the resident tissues. The main role of TRM cells is to provide superior protection against infection in extralymphoid tissues.
