Thekey differencebetween antigen and pathogen is thatantigen is a foreign substance, toxin or a molecule that can stimulate an immune response in order to produce antibodies against it while pathogen is an organism, especially a microbe, that infects our body and causes diseases. Pathogens are an...
Answer and Explanation: Pathogens are small agents that produce disease in our body. They are the things that make us sick. It is a microbe. Usually it will be a virus or bacteria. An antigen is a protein that (when it enters our body) results in an immune response from the body. ...

4. These results indicated that vaginal DCs were the antigen presenting cells which present brucella antigen to naive T lymphocytes, leading to the release of IFN-γ. Brucella spp. is an intracellular pathogen that preferentially infects macrophages. The macrophages in vaginal mucosa of BALB/cmice...

What is one difference between rabies virus and influenza virus? Explain the differences between antigens and antibodies and their roles in the immune system. Describe how different pathogen recognition receptors ensure that a variety of different pathogens, both intracellula...
Once degradation is complete, leftover waste products are excreted from the cell in an exocytic vesicle. However, it is important to note that not all remains of the pathogen are excreted as waste. Macrophages and dendritic cells are also antigen-presenting cells involved in the specific adaptive...
Human monocytes are integral to the innate immune response and pivotal in first-line defenses such as phagocytosis, cytokine and chemokine release, and antigen presentation1. Activation of monocytes is triggered by pattern recognition receptors (PRRs) that sense conserved pathogen-associated molecular patt...
The influenza A virus provides a much studied example: its surface proteins (antigens) are under strong selection by host immune responses and their molecular evolutionary shifts trigger recurrent epidemics and occasional pan- demics [1,2]. In this context, a strain may be defined simply by ...
Indeed, links between certain MHC alleles and supertypes (i.e., groups of alleles that show similar antigen-binding properties and are therefore assumed to be functionally similar) and lower parasite load and/or survival have been reported in diverse wildlife species (e.g., Schwensow et al. ...
