In an immunological synapse the membrane between the antigen presenting cell (APC) and the t cell touch. They exchange signals so the APC can present an antigen to the t cell. In this case the APC is a dendritic cell that has the right antigen for the t cell and love is in the air. …
This monocyte turned into a dendritic cell (DC) and doesn’t even know how it happened! Many researchers isolate monocytes and then derive them into DCs to do studies on these cells. It is a common method followed by people studying DCs that need to generate some cells for their experiments. In case you are interested in …
The dendritic cell (DC) is presenting an antigen to a T cell but the T cell doesn’t recognize it. This is making the DC kind of sad. In this case the DC is presenting the antigen on an MHC-I molecule and it is showing to a CD8 T cells. However, the T cell will recognize and …
A big challenge of the immune system in the intestine is being able to distinguish between harmful pathogens and at the same time be tolerant towards harmless antigens derived from food and commensal bacteria (good bacteria). Mechanisms to maintain tolerance are therefore necessary to avoid unwanted immune responses that may lead to inflammatory bowel diseases (IBD) …
Dendritic cells (DCs) are named after their branched projections called dendrites. These cells are the sentinels of the immune system and are always testing their surroundings in case they see any danger. DCs process antigens they pick up from their surrounding and present these to T cells. This video shows how dendritic cells …
