I)What T cell subset would be stimulated by a virus? Why?
J)What are cell adhesion molecules (CAMS) and how are they used by leukocytes? Give an example of a cell adhesion molecule.
Homework Answers
J) CAMS are the protein found on the cell membrane of the cell which helps them to bind them to the other cells present near to them present in the extracellular matrix..!! The example of cell adhesion molecules are integrin, cadherins, selectins..
The use of CAMS in leukocytes is the it helps in extravasation of the leukocytes from the circulatory system to the tissue whre the tissue damage or infection had occurred which is the first line of defense in the body among the pathogens..!! The movement occurs by the process of diapdesis..!! The example of CAMS used hre is integrin..
I) The T-Cells affected by the viruses are mostly the T-helper Cells which has Cd-4+ receptors present on them.. When the virus enter into the body it is the T-helper cells which recognize the virus or the antigen and gives signals to the other immune cells of the body.. Hence those cells are affected first to lower down the immune system of the body

Adaptive Immunity: Second Line of Defense—Cellular Defenses The T-cell receptors and CD4 and CD8 molecules interact with major histocompatibility complex (MHC) proteins. MHC proteins are found on most cells of the body. There are two variations, or classes, of MHC proteins. MHC class I is expressed on the surface of most cells of the body such as skin cells, liver cells, and others. Should a cell become infected with a virus, viral antigens are processed in the cells and expressed...

You have come down with a nasty cold and would like to understand why the virus that infected you is making you feel so lousy. With a few basic facts, given here within the problem, you can show that each infected cell is now very full of virus particles, resulting in your current condition. a. Given that a typical cell is about 10 μm in diameter, calculate its volume in liters. b. Find the concentration (in Molarity) of a single...

1. Consider a dilute solution of molecules at fixed temperature T. These molecules have access to a surface that has a total of B binding sites where molecules can bind. To count states in this system, we will divide space into small cells that each can hold a single molecule. There are a total of B cells that have a binding site, and a total of M cells that do not have binding sites. The overall number of cells is...

We briefly discussed the Herpes simplex virus (HSV) recently. I would like for you to write about this virus. Go into some detail about the differences between the two types. Here are a few discussion suggestions you can use during this: –How is it able to lie dormant in someone for years and then resurface again? –How does HSV avoid the immune response during the time it is dormant? –If you are working with the public what do you think...

You are a T-helper cell in your immune system and are deciding what parts of the immune system to marshall against an incoming invader. For this assignment, you will be presented with a pathogen and its arsenal of virulence factors that it can use against you. Your job, if you choose to accept it, is to pick the portions of the immune system that you will use against each virulence factor and then describe how that immune system part inactivates...
