| A | B |
| Interleukins | Communicate between cells. Play a role in inflammation and immune responses. |
| Interferons | "interfer" with viral replication. Activate NK (Natural Killer) cells. |
| Tumor Necrosis Factor (TNF) | Activates neutrophils and endothelial cells. Induces inflammation. Kills cells through apoptosis. |
| Growth Factor | Simulates production of plasma cells. |
| Natural Killer (NK) cells | Can destroy tumor cells or virus infected cells without previous exposure |
| Phagocytic Cells | Neutrophils and Macrophages |
| Presenter cells | Macrophages and Dendrites |
| The first line of defense | Physical barriers like skin, mucous membranes, GI tract mucous |
| Innate Immunity | An immune response not specific to the type of invader. |
| Humoral Immunity | B cells |
| Cell Mediated Immunity | T cells |
| CD4 | Stimulates B and T cells. Activates T cell response. |
| T suppressor cell | Helps decrease immune responses. |
| Thymus | Where T cells mature. |
| Bone marrow | Where B cells mature. |
| Immunoglobulins | B cells that have matured. |
| IgG | Most common immunoglobulin also crosses placenta. |
| IgM | First immunoglobulin on the scene. |
| IgE | Immunoglobulin seen in allergies. |
| IgA | Found in secretions like breast milk. |
| HLA (Human Leukocyte Antigen) | Recognizes self from non-self. |
| Adaptive Immunity | Recognizes self from non-self. One antigen to one antibody. |
| Titer or serology | Presence of antibodies |
| Passive Immunity | Temporary immunity |
| Seroconversion | Point where person tests positive for antibodies. |
| Window period | Point from inital infection to when patient tests positive for HIV antibodies. |
| CD4 | Cell that HIV attacks. |
| Diagnostics for HIV/ AIDs | ELISA, Western Blot, PCR |
| CD4 < 200 cells | Now AIDs |
| Opportunistic Infections | PCP, TB, CMV, Karposi's Sarcoma |
| Type I Hypersensitivity Reaction | Allergies |
| Type II Hypersensitivity Reaction | Cytotoxic - Incompatible blood types. |
| Type I Hypersensitivity Reaction | IgE, mast cells, basophils |
| Type II Hypersensitivity Reaction | IgG, IgM |
| Type III Hypersensitivity Reaction | Antigen-Antibody Complexes that cause tissue damage. |
| Type III Hypersensitivity Reaction | Post strep glomerulonephritis |
| Type IV Hypersensitivity Reaction | Cell mediated |
| Type IV Hypersensitivity Reaction | Poison ivy, TB test |
| Latex allergy | IgE or T cell mediated. Reaction to protein in Latex. |
| Bananas, Kiwis, Avocados, Tomatoes | Cross sensitivity to Latex. |
