# The individual's B cells would not be able to mediate isotype switching.
The individual's B cells would produce primarily IgM antibodies.
The individual's B cells would not be able to isotype switch from IgM to IgD.
This gene involves in the somatic hypermutation, class switch recombination and gene conversion.

Hi, for the question, please fill it yes or no for each part bolded. Susan and Joe were worried. Their little boy, Daniel, had been having an awful lot of bacterial infections and he was barely a year old. It seemed that the antibiotics cleared up one bacterial respiratory infection only to have another follow shortly. The scary thing was that Daniel had just fought off a case of pneumonia caused by Pneumocystis carnii, a fungal infection that was usually...

1.One group of immune deficiency diseases is caused by an inability of CD8 effector T cells to kill virus-infected target cells, due to defects in cytotoxic vesicle exocytosis. Because of the inflammatory response that accompanies a normal virus infection, together with the prolongation of this response due to the inability to control the infection, patients with these disorders suffer from tissue damage caused by the infiltration of effector CD8 cells and activated macrophages into multiple organs. In addition, a subset...
Indicate what step is correct (Select all that apply) Lymphocytes travel through the body in the lymph as well as the blood Lymphocytes leave the blood through the walls of fine capillaries in 2ry lymphoid organs After spending some time in the LN, lymphocytes leave in the efferent lymph Lymphocytes return to blood at the subclavian vein A lymphocyte after encounter an antigen to which its receptor binds, stops recirculating. The spleen has no connection to the lymphatic system Lymphocytes...
