Anti-asparaginyl tRNA synthetase (Anti-KS) antibody-positive pneumonitis in a patient with immune checkpoint inhibitor treatment: A case report and literature review.

In recent years, the use of immune checkpoint inhibitors (ICI) has increased and there have been case reports of anti- aminoacyl tRNA synthetase (ARS) antibody syndrome during ICI treatment. However, these cases are limited, and their clinical characteristics are not fully understood. We report the first case of anti ARS antibody syndrome with KS antibody during ICI therapy.

Altered Immunohistochemical Expression Patterns of HLA Class I during the Clinical Course of Cervical Intraepithelial Neoplasia.

It is unclear how immunohistochemical expression patterns of HLA class I in the pre-malignant phase of cervical intraepithelial neoplasia (CIN) alter during the clinical follow-up period. The present study aimed to demonstrate the correlation between the immunohistochemical expression pattern of HLA class I and the CIN grade through repeated examinations during the clinical course. Expression patterns of HLA class I, p16INK4a, and PD-L1 were immunohistochemically examined using formalin-fixed paraffin-embedded (FFPE) sections of biopsy or conization samples that were obtained from 20 patients diagnosed with CIN.
