What does the primary immune response involve and produce?

Immune responses to antigens may be categorised as primary or secondary responses. The primary immune response of the body to antigen occurs on the first occasion it is encountered. The humoral response, mediated by B cells with the help of T cells, produces high-affinity and antigen-specific antibodies.

Keeping this in consideration, what is the primary immune response?

The primary immune response occurs when an antigen comes in contact to the immune system for the first time. The secondary immune response occurs when the second time (3rd, 4th, etc.) the person is exposed to the same antigen.

Likewise, what are the 4 phases of the immune response? Definition 1. Lag phase 2. Exponential phase 3. Steady state phase 4. Decline phase Term What cells allow T cells to form into effector T cells and B cells to form into plasma cells? Definition Helper T cells

Regarding this, which is produced in primary immune response?

They have different roles in immune responses; IgG, IgA, and IgM are commonly produced after viral infection. During the first encounter with a virus, a primary antibody response occurs. IgM antibody appears first, followed by IgA on mucosal surfaces or IgG in the serum.

What makes a secondary immune response faster than a primary immune response?

Antigen-specific T cells are selected during a primary immune response and expand to produce clones of T cells with high specificity for the activating antigen. In a secondary response to the same antigen, memory cells are rapidly activated. This process is quicker and more effective than the primary response.
