Lymphocytes predominantly express the CD11a/CD18 integrin heterodimer (αL/β2, which is also known as leukocyte function-associated antigen-1 or LFA-1).[35] We used flow cytometry to assay baseline integrin expression and to compare expression between cell lines derived from patients with schizophrenia versus normal controls. This evidence concerns the gene ITGAL and schizophrenia.
