The innate immune system has to be able to detect foreign invaders. Explain two ways that the innate immune system is able to detect these foreign invaders to allow a response to be mounted.
One beautiful warm day in June, you are on a picnic and are stung on your finger by a bee. Although it hurt a little, you are soon enjoying the early summer day. The next morning you wake up to fi nd that your finger is swollen, quite stiff, red, and warmer than the rest of your fi ngers. In addition, you seem to have a bit of a fever.a. Which parts of the immune system seem to be activated?b. Which classic responses to injury did you experience?c. Explain which cytokines and cell types were probably most responsible for manyof your symptoms.

- Virus infections induce production of interferons that act on infected cells to enhance their recognition by CD8 cytotoxic T cells. To counter these mechanisms, viruses often encode proteins that interfere with antigen processing and presentation. In an experiment, cells infected with Virus X are treated with interferon and compared with uninfected cells treated with interferon. Proteasomes are isolated from the two cell populations and their enzymatic activities are compared. The data in figure below show the amino acid preferences for cleavage of peptides by the two samples of proteasomes. Based on these data, Virus X most likely encodes a protein that interferes with: The expression of MHC class I on the surface of the infected cell The rate at which peptides are produced from intact proteins in the infected cell The transport of peptides from the cytosol to the endoplasmic reticulum in the infected cell The replacement of constitutive proteasome subunits with immunoproteasome…arrow_forwardA friend was recently diagnosed with strep throat.
