Expression of neuroligin (NL)-2 in islets. To determine whether neuroligin-2 and neuroligin-3 proteins are expressed in islets, Western blot analysis was performed using rabbit polyclonal antibodies to neuroligin-2 (A) and neuroligin-3 (B). A, Neuroligin-2 was detected in human brain, human colon, and human islet cell lysate. Possible low-level expression was also observed in the testes cell lysate. B, Neuroligin-3 was only detected in human brain.
