The Role of the Eyelids of the Black-Winged Kite, Elanus caeruleus in the Immune Protection of the Eye.

This study aimed to describe the morphological features and microstructure of the upper, lower, and third eyelids of the black-winged kite, Elanus caeruleus, and to characterize the organized lymphoid follicles and lymphocytes in the eyelid mucosa. Additionally, it aimed to illustrate the importance of the eye adnexa in the eye's immune protection. The upper, lower, and third eyelids display varying morphological differences that seem to be closely linked to the birds' way of life, indicating adjustments to their environment and eating behaviors.

Coinfection of some respiratory viruses in cattle: An abattoir study.

To investigate the existence of bovine viral diarrhoea virus (BVDV), parainfluenza virus 3 (PIV-3) and respiratory syncytial virus (RSV) as well as its coinfections, a total of 420 pneumonic lung tissue samples were collected from slaughterhouses in three different areas. Samples were examined for the three viruses using antigen detection enzyme-linked immunosorbent assay (ELISA) test, and positive results were further confirmed using fluorescent antibody test and polymerase chain reaction. Prevalences detected were 10.

BATF-dependent Th17 cells act through the IL-23R pathway to promote prostate adenocarcinoma initiation and progression.

Background: The role of Th17 cells in prostate cancer is not fully understood. The transcription factor BATF controls the differentiation of Th17 cells. Mice deficient in Batf do not produce Th17 cells.

Pathobiological signatures of dysbiotic lung injury in pediatric patients undergoing stem cell transplantation.

Hematopoietic cell transplantation (HCT) uses cytotoxic chemotherapy and/or radiation followed by intravenous infusion of stem cells to cure malignancies, bone marrow failure and inborn errors of immunity, hemoglobin and metabolism. Lung injury is a known complication of the process, due in part to disruption in the pulmonary microenvironment by insults such as infection, alloreactive inflammation and cellular toxicity. How microorganisms, immunity and the respiratory epithelium interact to contribute to lung injury is uncertain, limiting the development of prevention and treatment strategies.
