<unk> s <unk> RLs) are a class of proteins that resemble<unk>  receptors. They have been characterized in a number of species, including humans and mice. They are preferentially expressed by B lymphocytes. Unlike the classical<unk>  receptors, there is no strong evidence that suggests that<unk> RLs bind to the<unk>  portion of antibodies. Their function is unknown. It has been indicated that<unk> RLs may be a unique marker for immune cells in the brain called microglia, compared to other CNS cells and peripheral immune cells.
