CD5 is a cluster of differentiation found on a subset of IgM-secreting B cells called B-1 cells, and also on T cells.
B-1 cells have limited diversity of their B-cell receptor due to their lack of the enzyme terminal deoxynucleotidyl transferase (TdT) and are potentially self-reactive.
CD5 serves to mitigate activating signals from the BCR so that the B-1 cells can only be activated by a very strong stimuli (such as bacterial proteins) and not by normal tissue proteins.
CD5 was used as a T-cell marker until monoclonal antibodies against CD3 were developed.
In humans, the gene is located on the long arm of chromosome 11.
There is no confimed ligand for CD5.
T cells express higher levels of CD5 than B cells.
CD5 is upregulated on T cells upon strong activation.
