- Recent studies have shown that people unexposed to and not infected with Covid-19 (caused by SARS-CoV-2 or Novel Coronavirus) may still exhibit T cell responses specific to other
Back to Basics:
What are B cells?
- These cells mature in the bone marrow and produce antibodiesin response to the antigens.
- B cells are involved in humoral response.
- As soon as B cells come across the antigens, they produce plasma cells and memory B cells.
What are T cells?
- T cells originate in the bone marow and mature in the thymus.
- These can be further divided into T helper cells and T cytotoxic cells.
- They are responsible for removing the pathogens from the body.
- As soon as the foreign antigen enters the cells,
- T cells trigger the B cells to develop plasma cells and activates T killer cells that kill the cells affected by the invaders.
Similarities between B cells and T cells
- Both B and T cells originate in the bone marrow.
- These cells are involved in adaptive immunity.
- They are a type of lymphocytes.
- The cells are nucleated and motile.
- Both protect the body’s immune system and help fighting infections.
- Both the cells are non-phagocytic and are a part of lymphatic system.
