Age-related changes in PHA and allogeneic reactivity of human T lymphocytes

|January 1, 1983
Abstract:
In fifty-four healthy individuals aged from 22 to 53 the response of lymphocytes to PHA stimulation and to stimulation with allogeneic lymphocytes were determined. A linear age-related decrease in reactivity to PHA (r = 0.500, P less than 0.01), as well as to allogeneic stimulation (r = 0.351, P less than 0.01) was found. The correlation between these two parameters of T lymphocyte function was weak (r = 0.207, not significant).

Cell-mediated Immune Responses
Overview
Cells of the Adaptive Immune Response
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...
B Cell Activation and Differentiation
The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
