The immune system is home to various cells, all of which have their own jobs to do when it comes to keeping the body functioning and healthy. Immune cells are broken up into several categorizations: lymphocytes, monocytes/macrophages, and neutrophils. Within the lymphocyte grouping, there are T-cells, B-cells, and natural killer cells.
T-cells are designed to start a reaction against specific pathogens, which then signals B-cells to start creating antibodies – proteins designed to help the body fight off pathogens. Natural killer cells are then tasked with activating receptors that lead to the production of small proteins that can kill the pathogen or limit its ability to spread throughout the body.
The immune system uses all of these cells to help keep you healthy. However, in some diseases or infections, levels of immune cells can change dramatically. One such cell is often negatively affected by disease: a natural killer cell known as CD57. But what is a CD57 cell marker? And how is it related to chronic illnesses such as Lyme disease?Continue reading “What Is A CD57 Cell Marker?”
