BRCA1 and pelvic inflammatory disease: Nakamura et al. also reported results using antibodies against BRCA1 phosphorylated at Ser1423 (pBRCA1 (Ser1423)) and at Ser1524 (pBRCA1 (Ser1524)), and showed that while tau aggregates were also positive for pBRCA1 (Ser1423) in all tauopathies, pBRCA1 (Ser1524) was mainly associated with Pick bodies in PiD [11].
