Michael Croft

Scientific Advisor at HiFiBiO


Michael Croft, Ph.D., and his team focus on a number of molecules that are members of the tumor necrosis factor (TNF) and tumor necrosis factor receptor (TNFR) family, a group of proteins believed to play important roles in the ability of the immune system to guard the body against harmful microorganisms, but that also may contribute to inflammatory and autoimmune diseases. The TNFR molecules studied by Dr. Croft and his laboratory are expressed on T lymphocytes. other cells of the immune system, and tissue cells such as epithelial cells and fibroblasts, and emerging evidence is suggesting they crucially regulate the function of these cells in many types of immune response.

Currently, four classes of drugs have been approved for clinical use that target molecules in the TNF and TNFR protein families. Dr. Croft’s laboratory is investigating the roles of other related molecules in several diseases, including asthma, atopic dermatitis, and scleroderma to determine if they could be targets for therapeutic intervention to suppress disease symptoms. Another line of research is investigating whether substances that can signal T cells and other immune cells through TNFR family proteins can be used to increase natural immune responses. This is particularly important for vaccination against viruses and diseases such as cancer, in which T cells do not function strongly enough or fast enough to combat the growth of the virus or growth of the tumor cells.

Dr. Croft is the primary inventor on a number of patents directed at autoimmune/inflammatory disease therapy targeting the TNF family and he has consulted for many major pharmaceutical firms. Dr. Croft is a Fellow of the American Asthma Foundation (formerly the Sandler Asthma Foundation). His research on OX40/OX40L interactions controlling the generation and activity of Th2 cells is cited by the Foundation as one of their major breakthroughs, and led to clinical trials of antagonists of OX40L in asthma, and of OX40 in atopic dermatitis.

Dr. Croft has been a member of the American Association of Immunologists (AAI) for many years and has served on the Nominating Committee that elects the members of the various committees of the AAI including the Council Members and President. He also programmed the Annual Meeting of the AAI for a period of 5 years serving as Block Symposia Program Chair; has been chair of several major symposia at the AAI annual meeting; and has been honored as invited speaker in the AAI President’s Symposium on two separate occasions. Dr. Croft has also been teaching faculty on multiple occasions on both the AAI Advanced and Introductory Immunology Courses. Dr. Croft has furthermore been on the Scientific Advisory and programming committee of the International TNF superfamily conference on several occasions. He has served on a number of NIH Study sections as a permanent member or ad-hoc. He has served as Associate Editor and Section Editor of the Journal of Immunology and Frontiers in Immunology, and was a member of Faculty 1000 prime.
