1. A. Identify the cells that display MHCI and MHC II proteins on their surface B. How are MHCI and MHCII similar? C. How are MHCI and MHCII different? 2. What type of testing is used to detect COVID-19? Include molecular and serological testing, principles, what the difference is between molecular and serological tests (such as what is being detected, etc..), as well the types of specimens required.

Compare/contrast MHC-I and MHC-II proteins, including the types of cells that display each.

Describe the structure of a class I MHC molecule AND a class II MHC molecule with the following prompts: a. number of polypeptide chains b. domains of each polypeptide chain, including transmembrane and cytosolic domains c. secondary structure d. domain composition of the peptide-binding site e. details of the architecture of the peptide-binding site f. size of the peptide that can bind

Which type of MHC class molecules is found on all nucleated cells and is used to...

Which type of MHC class molecules is found on all nucleated cells and is used to communicate with cytotoxic T-lymphocytes? Which class is found only on APCs and is used to communicate with helper T-lymphocytes? Where does a lymphocyte typically encounter an antigen for the first time? Describe how both helper T-lymphocytes and cytotoxic T-lymphocytes are activated. Is a separate APC required for B-lymphocyte activation, or is a B-lymphocyte able to serve the role of an APC? What are the...

1) Class II MHC molecules are found on which of the following? liver cells and macrophages in the spleen granulocytes and microphages red blood cells lymphocytes and antigen-presenting cells all body cells with a nucleus 2) Histamine increases blood flow and vascular permeability. This would account for all of the following changes that occur during inflammation except heat of the inflamed tissue. swelling of the inflamed tissue. movement of defense proteins and cells into the interstitial space. chemotaxis of phagocytes....
