Question

Fill in the correct term for each sentence describing the initiation of the immune response. interleukin-1 MHC proteins CD8 receptors Every cell in the body carries marker proteins on its surface called When foreign microbes enter the body digest the microbe and display antigens on the MHC proteins will partially humoral can detect body cells with Phagocytic cells called antigens stuck to the MHC proteins or foreign cells, which lack the correct "self MHC proteins macrophages After detecting antigens or foreign cells, macrophages initiate the immune respone and release a chemical alarm signal called cellular complement proteins The alarm signal released by macrophages stimulates the action of cytotoxic antigen-presenting cellsH Helper T cells then initiate two ines of immune defense the response which is carried out by T cells and the response which is carried out by B cellis helper T cells neutrophils

Explanation / Answer

1) when foreign microbe enter the body, antigen presenting cell partially digest the microbe and display antigen on the MHC protein. This process antigen bound to MHC interact with T Cell CD receptor, result in distruction of foreign microbe.

2) Phagocytic cell called macrophages can detect body cells with antigen stuck to MHC protein or foreign cell, which lack the correct self MHC proteins.

3) helper T cell intiate two lines of immune defence

Cytotoxic response which is carried out by T cell

Humoral response which is carried out by B cell

helper T cell recognize processed antigen bound to MHC II and release cytokines that activate cytotoxic T cell which destroy cancerous and infected cells, this is called cytotoxic response. Helper T cell interact with B cell so it differentiate into plasma and memory cell. Plasma cell secrete antibody and this is called humoral response.

After detecting antigen or foreign cell , macrophage intiate the immune response and release a chemical alarm signal called interleukin-1

Alarm signal release by macrophage, stimulate the action of helper T cell.

Every cell in the body carries marker protein on its surface called MHC protein. MHC1 present on all nucleated cells but MHCII is present on some specialized cell.
