Ppt B Cell Generation Activation And Differentiation Powerpoint
Ppt B Cell Generation Activation And Differentiation Powerpoint This document discusses b cell activation, differentiation, and memory. it defines b cells as lymphocytes involved in humoral immunity that develop in the bone marrow and express b cell receptors on their surface. B cell activation • depending on antigen, b cell activation proceeds by two different routes. • thymus dependent (td) antigens require direct contact with th cells to activate b cells.

The development process of b cells can be divided into three stages: generation of mature b cells, activation of mature b cells by antigen, and differentiation into plasma cells and memory b cells. Progenitor b cells (pro b cells) bearing a cd45r marker develop – in the bone marrow – into immature and then mature b cells. then, they migrate to peripheral lymph nodes. B cell activation by t cell • the activation of b cells by antigen binding to receptor and by coreceptor binding creates conditions for proliferation and differentiation of b cells.

The gc reaction generates memory b cells and plasma cells that produce high affinity antibodies, which are necessary to protect against invading microorganisms. If a cd4 helper t cell recognizes the antigen that is displayed on the b cell surface (i.e. that is being presented on class ii mhc by the b cell), the two cells interact, forming a tight t b cell conjugate. Cd40 mediated stimulation of b cells also synergizes with il 4 receptor (il 4r) signals to enhance the transcription of c germline transcripts (c glts) and activation induced cytidine deaminase (aid), rearrangement of the ige genomic locus and production of ige antibodies.
