MS is associated with what specific hypersensitivity reaction?
T cell mediated cytotoxicity
What is the theory that the rise in chronic inflammatory disease, especially allergies and asthma is an unintended consequence of a reduction in exposure to microbes in the first year of life?
What type of hypersensitivity reaction occurs within minutes or hours?
How is TB contracted?
Cell mediated cytotoxicity is mediated by what?
CD8 killer T cells
What is the "anti onco" gene that prevents tumors?
What type of hypersensitivity reaction uses T cells?
What is released by mast cells in the early phase?
Vasoactive amines (histamine), proteases, prostaglandins
What condition is caused by defects in immune regulation ?
What is the number 2 cause of death?
What are pathologic conditions caused by a normal immune response?
What gene is an accident waiting to happen?
In vitro what cells can destroy some cancer cells?
Lupus and Rheumatoid arthritis are associated with what type of hypersensitivity ?
What is a mutated chromosome 22 called?
Will someone always have an initial allergic reaction to the first exposure?
No, it takes a while for the IgE antibodies to accumulate
What hypersensitivity reaction is antibody mediated but depend on complement to do the killing?
What cells response is delayed during an allergic reaction?
MS is initiated by what?
Self reactive T cells
What type of hypersensitivity reaction is known as allergies?
How many mutations are required to produce cancer?
What type of hypersensitivity is stimulated by intracellular parasites?
Secondary exposure to an allergen will activate what cells?
What is MPDL3280A
Manufactured antibody that targets a progestin called PD-L1
What is the observation of both tumor inhibiting and tumor enchanting process mediated by the immune system?
What is it called when lymphocytes attack non self and SELF?
Which type of hypersensitivity reaction is immediate?
What hypersensitivity reaction is antibody mediated?
During an allergic reaction what cells are recruited from bone marrow (t helper secreting IL-5) ?
