cell-mediated immunity

n.
Immunity involving cells, such as T cells and phagocytes, in contrast with humoral immunity, which involves soluble proteins (antibodies). Also called cellular immunity.

cell′-me`diated immu′nity


n.
immunity conferred to an individual through the activity of T cells, involving the direct destruction of viruses, foreign particles, etc. Compare antibody-mediated immunity.

The pathogenesis of immunodeficiency and predisposition to infection in CLL are multifactorial, with primary CLL-related risk factors identified as hypogammaglobulinemia, defect in cell-mediated immunity, defective neutrophil function, increased length of disease (longer duration correlates with increased risk of severe infection), and advanced stage of disease [7].
"Previous studies in animals and simple model organisms over the past 85 years have supported the notion that calorie restriction can increase the lifespan by reducing inflammation and other chronic disease risk factors, but with mixed results about whether it has a negative or null effect on cell-mediated immune responses," said first and corresponding author Simin Nikbin Meydani, D.V.M., Ph.D., director of the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts (HNRCA) and the director of its Nutritional Immunology Laboratory.
The indication of these findings, the authors conclude, is that cell-mediated immunity is affected by ZV and enhanced by a stronger, or more recent, dose.
