The lost of self tolerance could be lead to
a) loss of cells necessarily to respond to infection
b) autoimmune diseases
c) allergies
d) exaggerated immune response to infectious agents
Homework Answers
Option b is correct because if self tolerance is lost body develop an autoimmunity against its own cells which causes autoimmune disease.

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...

1. The prevention of inflammatory immune responses to inhaled antigens in healthy individuals has mechanisms in common with those that prevent inflammatory immune responses to commensal microbes in the gut. One important component of immune regulation shared by these two situations is: a. The induction of increased numbers of IFN-g-producing T cells and ILCs in the airway and gastrointestinal epithelium b. The presence of tissue-resident mast cells that bind IgE through the high affinity IgE receptor c. The high levels...

Question 10-12
10. During the mating process, yeast cells respond to pheromones secreted by other yeast cells. These pheromones bind GPCRs on the surface of the responding cell and lead to the activation of proteins inside the cell. When a wild-type yeast cell senses the pheromone, its physiology changes in preparation for mating: the cell stops growing until it finds a mating partner. If yeast cells do not undergo the appropriate response after sensing a pheromone, they are considered sterile....
