Students have asked these similar questions
Explain why each choice (a-d) is correct or incorrect.
Allergens differ from antigens because
a. Allergens produce an abnormally large immune response to what is an otherwise harmless particle.
b. Allergens do not involve the leucocytes, they simple stimulate the inflammatory response.
c. Allergens are only active seasonally and are generally harmless to the body.
d. Allergens are primarily plant derived while antigens are bacterial or viral in nature.

A. ability to cross the placenta
B. isotype (class of antibody)
C. ability to fix complement
D. affinity for drug
Which of the following is NOT a way that an antibody can destroy a bacterial cell?

Antagonism b. Synergy c. Redundancy d. Pleiotropyarrow_forwardResearchers can make monoclonal antibodies by immunizing a mouse with a molecule (or with a microorganism). The resulting antibody-mediated response produces a set of antibodies that recognize different parts of the molecule. The mouse's B cells are then harvested from its spleen and fused with cancerous B cells from a myeloma cell line. The resulting hybrid myeloma ("hybridoma") cells are cloned: Individual cells are grown in tissue culture as separate cell lines. Each cell line produces and secretes antibodies that recognize one part of the immunizing molecule. These antibodies are called monoclonal antibodies, and they can be purified and used for research or other purposes. Monoclonal antibodies are effective for passive immunization, but only in the immediate term. Antibodies produced by one's own immune system can last up to about six months in the bloodstream, but monoclonals delivered in passive immunization often last for less than a week.

- Tuberculosis is a chronic respiratory condition caused by Mycobacterium tuberculosis, a high contagious bacterium. People with tuberculosis will often have a persistent (sometimes bloody) cough, fatigue, weight loss, and fever. M. tuberculosis produces a protein we will call “X”. A new test for tuberculosis checks for X antibodies in a person’s blood. If the antibodies are present, the result is “positive.” Why would X antibodies be present in someone’s blood? What specific kind of cells would produce them?arrow_forwardWhat class of antibodies is normally found in the mucosa of the respiratory tract? a. IG-A b. IG-D c. IG-M d.

The researcher decides to extract the antibody concentrated plasma and deliver it to a patient with HIV. What would you likely expect to see? a. The HIV patient will now have a fighting chance to eliminate HIV as the antibodies will not discriminate and bind to the same viral antigenic determinants. b. The HIV patient will form antibodies against the rabbit serum antibodies. c. The rabbit antibodies will opsonize the HIV antigenic determinants on the MHC II. d. The rabbit antibodies will never work because HIV in humans are different than HIV in rabbits.arrow_forward
