A single lymphocyte will have a receptor with a? - Single specificity. One cell may have many receptors (~120,000) but all will recognize the same epitope. Adaptive Immune system - •Takes longer to develop (~7 days) •Is highly specific for antigens, including those associated with microbes •Uses one type od receptor to recognize many different pathogens •Primary immune response = first time the adaptive immune response is activated against a pathogen. •Secondary immune response =...

Who discovered vaccination, how did he do it? correct answersIn 1796 Edward Jenner realized milkmaids who had contracted cowpox (mild disease symptoms compared to smallpox) were not susceptible to smallpox, so he used fluid from a cowpox pustule would induce immunity to smallpox and tested theory on 8 yr old boy- inoculated boy with fluid from cowpox pustule then later injected the boy with smallpox. The boy didn't contract smallpox. What are some gram - bacteria to know for this class? corr...

Describe Type I vs Types II interferons? - Type I interferon is secreted when a human cell is infected with a virus, interfere with viral replication, alert immune system cells that an infection is present, make virally infected cells more vulnerable to killer lymphocyte attack, Type I interferon inducing proliferation of NK cells, Type II interferon (interferon gamma) secreted from NK cells, CD8T cells and CD4 TH1 cells What cells can produce Type I interferon? - Almost all nucleated cells...
