These cytokines cause "killer" T lymphocytes and macrophages to flock to the antigen-presenting cell in an attempt to eliminate it. B cells activate humoral immunity, whereas T cells activate cell ...

The proliferation of antigen-specific lymphocytes and resulting clonal expansion are essential for adaptive immunity. We report here that B cell–specific deletion of the heavy chain of CD98 ...

Humoral immune responses are sexually dimorphic. Female individuals generally exhibit more-robust antibody responses to vaccines and, in the clinical setting as well as in experimental models, are ...

One of our defense system's most important strategies involves B lymphocytes ... B cells play a central role in adaptive immunity and, together with T cells and components of the innate system ...

Although the latter findings could have been seen as supporting the existing view that one type of lymphocyte was responsible for both cell-mediated and humoral immunity, the studies conducted by ...

In a recent study posted to the Research Square* preprint server, researchers explored the molecular basis for increased immunity against ... (CD19+) CD27+ memory B lymphocytes (MBCs) binding ...

To fight off viral and bacterial invaders, immune cells known as lymphocytes generate antibodies that specifically recognize and bind to these invaders, neutralizing them directly or marking them for ...

Types of lymphocytes There are two main types of lymphocytes: B cells (B lymphocytes). These make antibodies. Antibodies can destroy foreign substances or tag them for attack. T cells (T lymphocytes).

However, the duration of humoral immunity and the role played by memory B cells remain poorly defined. We performed a longitudinal analysis of antibody titers specific for viral antigens (vaccinia ...

A diagram showing humoral and cellular immunity. During this differentiation, memory B cells and effector B cells produce the same antigen-specific molecules as their parent naïve B cell. With the ...
