Some pathogens don’t activate the third line of defense. Can you think of a way in which pathogens can avoid detection by the adaptive immune response?

Which of these is an incorrect description of either the adaptive or innate immune responses?   Innate immunity involves both surface barriers and internal defenses. Only adaptive immunity involves defense against a specific foreign invader. Inflammation is an innate immune response but not an adaptive immune response. Chemicals are involved in adaptive immunity but not innate immunity. Immune system cells play a role in both innate and adaptive immune responses.

Which of the following is true about the adaptive immune system? Check all please. Adaptive immunity develops several days after the initial infection, but eliminate pathogens in a specific manner and is saved as memory to encounter the same reinfection Adaptive immunity is improved with repeated infections with the same pathogen A robust primary adaptive immunity can be generated in the absence of innate immunity Adaptive immune cells are B cells that make antibodies and T cells that eliminate infected cells and make cytokines Dendritic cells present antigens to T cells, whereas macrophages present antigens to B cells.

Innate Defense Briefly describe the role of each in our innate defense system.. skin inflammation Турe here... Type here... mucous membranes fever Type here... Турe here... phagocytes natural killer cells Type here... Type here...

match the following with their partners: herd immunity the faster and more robust immunity that occurs after vaccination antigen presenting cell what is primed and used in a cellular vaccine secondary immunity making it unlikely a contagious person can contact a vulnerable person memory B cell a long-lived cell that can activate to produce antibodies killer T cell a cell that can kill infected cells

Johnny has just been infected and needs your help in letting him know how his body is fighting the infection. To do so, describe how the innate and adaptive immune systems work together. You should address the following: 1. define adaptive and innate immunity; 2. Describe the role of natural killer cells (how do they work); 3. what are antigen presenting cells and what is their function, what are MHCs?; 4. describe the role of the complement system; 5. what is the role of interferons?; 6. How do helper T cells, cytotoxic T cells and B lymphocytes work make sure you address adaptive immunity memory?; 7. Define HIV, which cells do they attack and why do some individuals develop persistent lymphadenopathy (swollen or enlarged lymph nodes)?

What part of defense would likely be affected if the pathogen contained a mutation in it's pathogen-associated molecular patterns (PAMPs)? the pathogen would secrete greater amounts of toxins. the pathogen might not be recognized by the host. the pathogen would be easily recognized by the host's TLRs. the pathogen would not be able to penetrate the host's physical barriers.
