Flow Chart Humoral & Cell Mediated Immunity

Flow chart showing the components of the specific immune response that shows the interaction and relationships of the cells in both humoral & cell mediated immunity.

Summary - TLR4 polymorphisms, infectious diseases, and evolutionary pressure during migration of modern humans.

I have been asked to write a summary of about 400 words on a scientific paper. I am not to include the papers method section. This is what is difficult. What points do I include? Any help would be appreciated. The article is; TLR4 polymorphisms, infectious diseases, and evolutionary pressure during migration of modern humans. ...continues

In vitro limiting dilution, measuring the number of B cells responding to the hapten TNP under various conditions.

This solution is an interpretation of an experiment that measures hapten-specific B cell response by limiting dilution assay. The explanation begins with a brief background on antigen-antibody response and the limiting dilution method to evaluate it. The effect of pre-exposure to hapten and the generation of hapten-specific B ce ...continues

How does the immune system sense the presence of a pathogen?

The immune system must be able to ignore normal human proteins, but be able to rapidly respond to infectious agents. The solution gives details about how the immune system can make this discrimination, which leads to the development of an immune response.
