Q

Extrafollicular reaction:

Germinal center:

Memory B cells

A
  • low levels of low-affinity antibodies in the serum after immunization
  • b cells differentiate into plasma cells secreting high affinity antigen specific antibodies
  • few plasma cells exit the nodes/spleen and travel to bone marrow

Q

T cell response ( 3 stages)

First stage
second stage
third stage

A
  • expansion phase, T cells expand into CD4 and CD8 cells
  • inflammatory cytokines and kill cells are secreted
  • Memory phase, # of T cells stabilize and cells are maintained
