Question

Class ii mhc proteins are found on which of the following cell types?

Answer 1

Class II MHC proteins are present on professional antigen-presenting cells such as macrophages, dendritic cells, and B cells.

Step-by-step explanation:

Class II MHC proteins are found on a specific group of cells within the immune system known as professional antigen-presenting cells. These include macrophages, dendritic cells, and B cells. Unlike MHC I molecules that are found on all nucleated cells, MHC II molecules play a crucial role in the adaptive immune response by presenting abnormal or nonself pathogen antigens to T cells, leading to their activation.

Answer 2

The answer to the question: Class II MHC proteins are found on which of the following cell types, would be: on macrophages and lymphocytes, particularly T-Cells.

Step-by-step explanation:

MHC, or Major histocompatibility complex, is a very important part of the immune response that the body gives against an invading pathogen, or other foreign substances. There are three types in the human body, Class I, Class II and Class III and each of them will play a role on the cellular membrance of different types of cells and mediate different types of responses. In the human body, this histocompatibility complex is best known as HLA, or human leukocyte antigen, and it will ensure the recognition, or non-recognition of substances, tissues, and other organisms, by the human immune system. Class II, as mentioned before, are most usually found on the immune cells macrophages and lymphocytes, and they are the ones responsible for presenting antigens to these proteinic antibodies so that the immune cells can initiate a proper immune response.
