Infection refers to the invasion and multiplication of a pathogen within the body, while inflammation is the body's protective response against infection. Inflammation is a complex process involving various types of immune cells, clotting proteins and signaling molecules, all of which change over time.

What is the difference between a nuclear response and a cytoplasmic response? A nuclear response involves the alteration of gene expression, while a cytoplasmic response involves the activation of an enzyme or the opening of an ion channel.

What's the difference between colitis and ulcerative colitis? Colitis means your colon is inflamed, or irritated. This can be caused by many things, such as infections from viruses or bacteria. Ulcerative colitis is more severe because it is not caused by an infection and is lifelong.

B cells have two main types of immune responses. In a T-Independent immune response B cells can respond directly to the antigen. In a T-dependent immune response the B cells need assistance from T cells in order to respond. ... They secrete antibody as an early attempt to neutralize the foreign antigen.

Which one of the following is the primary difference between an anaphylactic reaction and an anaphylactoid reaction? An anaphylactoid reaction may occur without prior sensitization to the antigen; anaphylaxis requires prior sensitization.

A virus is acellular (has no cell structure) and requires a living host to survive; it causes illness in its host, which causes an immune response. Bacteria are alive, while scientists are not yet sure if viruses are living or nonliving; in general, they are considered to be nonliving.

What is the difference between a reactive response and an anticipatory response in hazard reduction? Reactive response (especially recovery) occurs after a disaster has occurred, while an anticipatory reaction occurs as preparation before a disaster occurs, for purposes of disaster preparedness.

Dialogue between the innate and adaptive immune systems is not one sided. Elements of the adaptive response also support the function of the innate immune system. For example, antibodies secreted by B cells bind to macrophages and other phagocytes by interaction with Fc receptors on these cells.

“In autoimmunity, there is a different type of T-cell involved than in allergies. In an autoimmune response, tissue destruction occurs. With allergies, the immune system overreacts to harmless allergens. Interestingly, this is the same type of response that expels viruses, parasites, and bacteria from the body.”

Cytokine is a general term used for all signalling molecules while chemokines are specific cytokines that functions by attracting cells to sites of infection/inflammation.

Innate immunity is something already present in the body. Adaptive immunity is created in response to exposure to a foreign substance. ... Once activated against a specific type of antigen, the immunity remains throughout the life.

Unlike chemotherapy, which acts directly on cancerous tumors, immunotherapy treats patients by acting on their immune system. Immunotherapy can boost the immune response in the body as well as teach the immune system how to identify and destroy cancer cells.

Humoral immunity secretes antibodies to fight against antigens, whereas cell-mediated immunity secretes cytokines and no antibodies to attack the pathogens. The Humoral immunity is rapid or quick in their action against antigens, while the Cell-mediated immunity show delay though permanent action against any pathogens.

While both are biomarkers for inflammation, ESR and CRP should be interpreted differently. Due to this basic physiologic difference, CRP is a more sensitive and accurate reflection of the acute phase of inflammation than is the ESR.

Immunogen is a stimulus that produces a humoral or cell-mediated immune response, whereas antigens are any substance that binds specifically to an antibody or a T-cell receptor.

Brain is not involved in elicitation of immune response. Lymph nodes are oval shaped organs of lymphatic system, distributed widely throughout our body and are garrisons of B,T and other immunity cells. The thymus is on specialised organ of immune system within which the T-cell nature.

What is the key difference between active immunity and passive immunity? In active immunity, a body produces its own antibodies; in passive immunity, a person receives pre-made antibodies.
