Questions Related to innate and acquired immunity
which of the following are necessary for the production of maximal humoral response upon initial exposure to a protein antigen?
-
B lymphocytes only
-
T lymphocytes only
-
B lymphocytes and dendritic cells only
-
B lymphocytes and T lymphocytes only
-
B lymphocytes , T lymphocytes and dendritic cells
B cells, otherwise called B lymphocytes, are a sort of white platelet of the lymphocyte subtype. They work in the humoral insusceptibility segment of the versatile safe framework by emitting antibodies.
Immunocompetence refers to the
-
ability of the immune system to distinguish self from non-self
-
differentiation, depending on location of lymphocytes into B- or T-cells
-
development of receptors on B- and T-cells that are specific for one particular antigenic determinant
-
ability of helper T-cells to recognize the major histocompatibility complex
Immunocompetence is the ability of the body to produce a normal immune response following exposure to an antigen. Immunocompetence is the opposite of immunodeficiency.
Primary and secondary immune response are carried out with the help of
-
B-Lymphocytes
-
T-Lymphocytes
-
Antiviral Proteins
-
Both A and B
The major difference between humoral immunity and cell-mediated immunity is that:
-
humoral immunity is non-specific, whereas cell-mediated immunity is specific for particular antigens
-
the agents of humoral immunity are carried in the bloodstream, whereas the cells of the latter are concentrated in lymph nodes
-
humoral immunity cannot function independently; it is always activated by cell-mediated immunity
-
humoral immunity acts against free-floating antigens, whereas cell-mediated immunity works against pathogens that. have entered body cells
The immune system has two divisions-humoral immunity and cell-mediated immunity. The humoral immunity protects against extracellular pathogens while the cell-mediated immunity protects against intracellular pathogens.
The cells that actually release antibodies are
-
Helper T-cells
-
Cytotoxic T-cells
-
Plasma cells
-
Suppressor cells
Activated B cells differentiate into either antibody-producing cells called plasma cells that secrete soluble antibody or memory cells that survive in the body for years afterwards in order to allow the immune system to remember an antigen and respond faster upon future exposures.
Control of the activated complement components results from
-
Agglutination
-
Immune adherence
-
Instability and inactivation of some of these components
-
Mobility of phagocytes
The activity of complement components is modulated by a system of regulatory proteins that prevent tissues damage as a result of inadvertent binding of activated complement components to host cells or spontaneous activation of complement components in plasma.
