Protease inhibitors K. Humoral immunity L. Cell-mediated immunityExplanation / Answer
B cells have mature in the bone marrow and then migrate to lymph nodes and other lymphatic organs. Each B cell has a unique antibody that binds with a specific to antigen and produces immune response. It is named as humoral immunity as it involves substances that are found in body fluids (or humors).
Infectious viral particles are produced by proteolytic cleavage action of protein precursors. Protease inhibitors block this action by binding to these specific viral protease and prevent the replication of virus.
Cell mediated immunity is a type of immune response that involves activation of cells like phagocytes, T lymphocytes, release of cytokines in response to antigen. There is no production of antibodies in this type of immunity.
The disease that is epidemic and prevalent across countries or the whole world are called Pandemic.
Protease is an enzyme that is responsible for proteolysis by hydrolysing the peptide bonds.
Prophylaxis is a kind of measure or treatment given to prevent disease.
Retrovirus is a group of RNA virus that inserts a DNA copy of their genome into the host cell for replication. (E.g. HIV)
Lymphocytes are special WBCs that run in lymphatic system and other lymphatic organs and produce immunity.
A foreign particle, substance or a toxin that triggers immune response in the body is called an Antigen,
The toxins released by foreign particles are detected by receptors on phagocytes, then they proceed to engulf and kill pathogens. They are of two types microphages (Neutrophils) and macrophages (Monocytes).
