Compare naive effector and memory T B cells survival time I

Compare naive, effector, and memory T & B cells (survival time, Ig & functions)

Solution

Answer=

1] Naive T cells =Naive T cell that has differentiated in bone marrow & successively undergone the positive & negative processes of central selection in the thymus

Naive B cells =Naive B cell that has been exposed to an antigen

2] Effector cells = are the relatively short -lived activated cells that defend the body in an immune response

Effector B cells called as plasma cells & secrete antibodies ,& activated T cells includes cytotoxic T cells & helper T cells which carry out cell mediated responses

3] Memory T B cells =

Memory T cells =1] develop in thymus either travel in the blood or lymphatic system or migrate to different organs in the body

helper T cells produces chemicals

some trigger B cells to to develop into plasma cells ,while others stimulate T cells to target & kill cells

2] survival time = T cells survive around for a long time after the immune response has finished

Memory B cells =

1] Cannot directly attack infected cells

they primarily produce antibodies they hijacks invaders as they travel in blood
