A virus invades the body through a break in the skin or another portal of entry. The virus must make its way _______ a cell in order to replicate itself.
A ____________ recognizes the antigens on the surface of the virus. The _____________ digests the virus and displays pieces of the virus (antigens) on its surface.
A ________________ cell recognizes the antigen displayed and binds to the macrophage. This binding stimulates the production of cytokines (interleukin-1 [IL-1] and tumor necrosis factor [TNF]) by the macrophage and interleukin-2 (IL-2) and -interferon ( IFN) by the T cell. These cytokines are intercellular messengers that provide communication among the cells.
T helper cell

T cytotoxic cells and natural killer cells _________ infected body cells.
The antibodies bind to the virus and mark it for ____________ destruction
Once the virus is gone, activated T and B cells are turned off by suppressor T cells. ___________ B and T cells remain behind to respond quickly if the same virus attacks again.

Bronchospasm, angioedema, and respiratory distress/collapse are immediate and life threatening concerns in anaphylaxis.
________ reactions: inherited tendency to become sensitive to environmental allergens. Examples: allergic rhinitis, asthma, atopic dermatitis, and urticaria.

Allergy testing may be necessary to determine the antigen causing the reaction. Persons undergoing allergy testing must be off systemic steroids, antihistamines, aspirin and NSAIDS for up to 5 days before testing.

2-3 days
Types of transplant rejection:
