BLNK is involved in B‐cell differentiation (Lagresle‐Peyrou et al., 2014) and is over‐expressed in B‐cell lymphoma in the CNS (Akhter et al., 2015) and may also have a role in modulating autoimmunity by regulating the production of IL‐10 (Jin et al., 2013). Here, IL10 is linked to B-cell non-Hodgkin lymphoma.
