Peter N. Devreotes is an American scientist and the Isaac Morris & Lucille Elizabeth Hay Professor [10] [11] and former director of the department of cell biology, [1] [8] with joint appointments in the Center for Cell Dynamics [12] and department of biological chemistry [13] at the Johns Hopkins University School of Medicine. [9] He also serves on the scientific advisory board of the Allen Institute for Cell Science. [14] He is best known for his contribution in the field of eukaryotic chemotaxis, signal transduction, and phosphoinositides biology. [1] [6] [7] [15]
Devreotes received his Bachelor of Science degree in physics from University of Wisconsin–Madison in 1971. He next earned his PhD degree in biophysics from the Johns Hopkins University in 1977, where he worked in the laboratory of Dr Douglas Fambrough. He then carried his post-doctoral research in Dr Theodore Steck laboratory at the University of Chicago. Devreotes started his independent career as an assistant professor at the department of biological chemistry]in the Johns Hopkins University School of Medicine in 1980. He was subsequently promoted to the rank of associate professor and then to professor. He served as the director of the biochemistry and molecular biology graduate program from 1990 to 2000. Then he was appointed as the director of the department of cell biology of the Johns Hopkins University School of Medicine in 2000. [9] [16] [17]
As an internationally recognized leader in cell migration, Devreotes was elected to the National Academy of Sciences. [7] He was elected and served as a council member of American Society for Cell Biology. [18] He served in the advisory of the Searle Scholars Program. [19] Devreotes founded Gordon Research Conference on "Gradient Sensing and Directed Cell Migration" in 2005. [20] He currently serves on the Scientific Advisory Board of the Allen Institute for Cell Science. [14]
Devreotes trained more than 75 doctoral students and post-doctoral fellows, many of whom have received senior and distinguished positions in major research institutes (such as University of Michigan, Perelman School of Medicine, Johns Hopkins University, Beatson institute, UTSW, Weill Cornell Medicine, NIAID ) and in different industry. [17] [ better source needed ] He authored more than 300 scholastic publications including research articles, reviews, book chapters. As of June 2023, he has an h-index of 94 on Google Scholar. [21]
Devreotes is an internationally recognized leader in the field of chemotaxis and signal transduction. [7] [11] [14] Devreotes was the first to identify the chemoattractant receptors and to demonstrate that multiple signalling events are activated asymmetrically at the cells leading edge which led to an understanding of the sophisticated strategies that cells use to precisely sense direction. [7] [22] Subsequent research in Devreotes lab helped to uncover the GPCR kinetics and phosphoinositides biology of the polarity organization in migrating Dictyostelium and leukocyte cells. [23] [24] Inside the scientific community, he is widely credited for bringing system-level understanding and implementing computational analysis of dynamical systems in different cell physiological processes. [1] His recent works[ as of? ] focus on the understanding the dynamics of internal feedback loops in signal transduction and cytoskeletal networks that confer the biochemical excitability to the membrane and thus control different morphological and functional properties of the cell. [1] [2] [25] [26]
Devreotes received several major awards and honors for his contribution to the cell biology and systems biology:
Chemotaxis is the movement of an organism or entity in response to a chemical stimulus. Somatic cells, bacteria, and other single-cell or multicellular organisms direct their movements according to certain chemicals in their environment. This is important for bacteria to find food by swimming toward the highest concentration of food molecules, or to flee from poisons. In multicellular organisms, chemotaxis is critical to early development and development as well as in normal function and health. In addition, it has been recognized that mechanisms that allow chemotaxis in animals can be subverted during cancer metastasis, and the aberrant change of the overall property of these networks, which control chemotaxis, can lead to carcinogenesis. The aberrant chemotaxis of leukocytes and lymphocytes also contribute to inflammatory diseases such as atherosclerosis, asthma, and arthritis. Sub-cellular components, such as the polarity patch generated by mating yeast, may also display chemotactic behavior.
Bonnie Lynn Bassler is an American molecular biologist; the Squibb Professor in Molecular Biology and chair of the Department of Molecular Biology at Princeton University; and a Howard Hughes Medical Institute Investigator. She has researched cell-to-cell chemical communication in bacteria and discovered key insights into the mechanism by which bacteria communicate, known as quorum sensing. She has contributed to the idea that disruption of chemical signaling can be used as an antimicrobial therapy.
Daniel Nathans was an American microbiologist. He shared the 1978 Nobel Prize in Physiology or Medicine for the discovery of restriction enzymes and their application in restriction mapping.
Martin Rodbell was an American biochemist and molecular endocrinologist who is best known for his discovery of G-proteins. He shared the 1994 Nobel Prize in Physiology or Medicine with Alfred G. Gilman for "their discovery of G-proteins and the role of these proteins in signal transduction in cells."
The Max Planck Institute of Biochemistry is a research institute of the Max Planck Society located in Martinsried, a suburb of Munich. The institute was founded in 1973 by the merger of three formerly independent institutes: the Max Planck Institute of Biochemistry, the Max Planck Institute of Protein and Leather Research, and the Max Planck Institute of Cell Chemistry.
Cell migration is a central process in the development and maintenance of multicellular organisms. Tissue formation during embryonic development, wound healing and immune responses all require the orchestrated movement of cells in particular directions to specific locations. Cells often migrate in response to specific external signals, including chemical signals and mechanical signals. Errors during this process have serious consequences, including intellectual disability, vascular disease, tumor formation and metastasis. An understanding of the mechanism by which cells migrate may lead to the development of novel therapeutic strategies for controlling, for example, invasive tumour cells.
Peter Walter is a German-American molecular biologist and biochemist. He is currently the Director of the Bay Area Institute of Science at Altos Labs and an emeritus professor at the Department of Biochemistry and Biophysics of the University of California, San Francisco (UCSF). He was a Howard Hughes Medical Institute (HHMI) Investigator until 2022.

Linzer was named provost of Northwestern University on September 1, 2007, until 2017 having previously served as Dean (2002–2007) and Associate Dean (1998–2002) of Northwestern's largest constituent school, the Weinberg College of Arts and Sciences.
Laura Lee Kiessling is an American chemist and the Novartis Professor of Chemistry at the Massachusetts Institute of Technology. Kiessling's research focuses on elucidating and exploiting interactions on the cell surface, especially those mediated by proteins binding to carbohydrates.

Understanding and manipulating these interactions provides tools to study biological processes and design therapeutic treatments. Kiessling's interdisciplinary research combines organic synthesis, polymer chemistry, structural biology, and molecular and cell biology.

In 2018, she was elected to the National Academy of Sciences and named a fellow of the American Academy of Arts and Sciences.
Elizabeth Dexter "Betty" Hay was an American cell and developmental biologist. She was best known for her research in limb regeneration, the role of the extracellular matrix (ECM) in cell differentiation, and epithelial-mesenchymal transitions (EMT). Hay led many research teams in discovering new findings in these related fields, which led her to obtain several high honors and awards for her work. Hay primarily worked with amphibians during her years of limb regeneration work and then moved onto avian epithelia for research on the ECM and EMT. Hay was thrilled by the introduction of transmission electron microscopy (TEM) during her lifetime, which aided her in many of her findings throughout her career. Moreover, Hay was a huge advocate of women in science during her lifetime.
