This is consistent with a recent report that microglial SWELL1 is not involved in ischemic brain injury.[31] In addition to SWELL1, other VRAC subunits (LRRC8B‐D) have also been shown to be highly expressed in the brain, except LRRC8E (Figure S1B, Supporting Information). The gene discussed is LRRC8B; the disease is brain injury.
