Apoptosis is a form of programmed cell death that plays a pivotal role in development and regulation of the immune system. However, it has become evident that apoptosis also plays a major role in a host of diseases including malnutrition, wasting, cancer, AIDS, Alzheimers, heart disease, stroke, neuronal damage, etc. MORE
Our lab has been a pioneer in the area of nutritional - immunology. We are interested in the fact that malnutrition and wasting have a rapid and adverse effect on the immune system. Thus, malnourished children as well as those suffering from cancer, AIDS, renal disease, chronic gastrointestinal disorders, etc., where malnutrition or wasting becomes a part of the disease have compromised immune systems.

Our lab is also interested in determining the changes in gene expression made by myeloid cells that enable them to survive natural stresses such as exposure to glucocorticiods (Gc) and/or malnutrition. Normally neutrophils have a short half life of 18 hours and readily undergo spontaneous apoptosis. Yet exposure to Gc, LPS, or some cytokines prolongs their life span. MORE
We have a state-of-the-art Becton Dickinson Vantage flow cytometer with two lasers making multiparameter analysis of fluorochromes from UV to red possible. MORE
