- How are B cells stimulated to make antibodies, what determines the isotype of antibody made and what are the different functions of these isotypes?
- what would be the immune response following infection with an extracellular bacteria?
Homework Answers
After binding of the antigen to the B cell receptor cause cell to divide and proliferate .some stimulated B cells become plasma cells which secretes antibodies.Another become memory cells which later time differntiatdi into plasma cells.
Antibodies are classified into 5 isotypes IgA, IgM, IgD, IgG, IgE etc. according to type of heavy chain they contain alpha, mu, delta, gamma, epsilon respectively. These are differ in constant domains, hinge structure and valncy of antibody.
In case of extracellular bacteria humoral immune response is given by activating T and B cell . B cell secretes antibodies against bacteria.

Alpaca Conventional antibody Alpaca heavy- chain antibody Nanobody/ VH CH1 VH Single domain antibodies are a type of antibody produced naturally by llamas and other camelids, which consist of only a single monomeric heavy chain or light chain but nonetheless can achieve equal binding affinity to antigens as conventional antibodies. A new product, called nanobodies, can be derived from single domain antibodies as depicted in the diagram. While their purpose in these animals is currently unclear, there is large commercial...

Immunology (elaborate explanations are not necessary 3-4 sentences are suffice) State timing, steps and cells involved in the innate immune response to bacterial antigens and contrast this with adaptive immune responses to the same antigen. Explain how macrophages recognize bacteria and the host mechanisms that lead to recruitment of cells to sites of infection. Explain how inflammation is triggered, the changes in cells at sites of infection that occur and how this relates targeting of both phagocytes and adaptive immune...

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...
