Abstract:
Aging represents a complex remodeling in which both innate and adaptive immunities deteriorate. Age-related changes in humoral immunity are responsible for the reduced vaccine responses observed in elderly individuals. Although T cell alterations play a significant role in age-related humoral immune changes, alterations in B cells also occur. We here provide an overview of age-related changes in B cell markers and functions. Our studies have shown that intrinsic changes in B cells with age contribute to reduced antibody responses such as those to the influenza vaccine.

B Cell Activation and Differentiation
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...

Special Features of Adaptive Immunity
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...
