Hello students, in this question we'll be just answering questions regarding different aspects of immune system.
00:07
So, first is about humoral immunity.
00:10
So, humoral immunity requires production of antibodies against the pathogen by utilization of the antigen presenting cells and different lymphocytes by their differentiation on exposure to antigen.
00:29
There is formation of mhc complex that recognizes the cd receptor on the t cells, specifically mhc 2 recognizes t helper cell and this happens when the t helper cell are recognized by the cd4 component on the t cells and now so this is the important characteristics.
01:03
Next is the plasma cells.
01:06
The plasma cells are differentiated b cells that are capable of producing antibody.
01:12
So, the t helper cell after activation produces, first activates the b cells and after activation differentiates into two categories.
01:26
One is plasma cells which produce antibodies and the memory cells which are kept as memory.
01:42
So, next answer is the immunoglobulin is a protein.
01:53
Immunoglobulin is protein with heavy and light chain for recognizing and binding to the foreign and pathogen.
02:11
It is the y -shaped structure.
02:17
Next is the classes of immunoglobulins are immunoglobulin g, immunoglobulin a, ige, igd and igm.
02:41
Next answer is regarding activation of immune cells...
