CNS expression of B7-H1 regulates pro-inflammatory cytokine production and alters severity of Theiler's virus-induced demyelinating disease. [PDF]
PLoS ONE, 2011 The CNS is a unique organ due to its limited capacity for immune surveillance. As macrophages of the CNS, microglia represent a population originally known for the ability to assist neuronal stability, are now appreciated for their role in initiating and

Temporal evolution of programmed death-ligand 1 expression in patients with non-small cell lung cancer [PDF]
The Korean Journal of Internal Medicine, 2021 Background/Aims Programmed death-ligand 1 (PD-L1) expression, a validated predictive biomarker for anti-PD-1/PD-L1 inhibitors, is reported to change over time. This poses challenges during clinical application in non-small cell lung cancer.

Human Rhinovirus Infection Enhances the Th2 Environment in Allergic and Non-allergic Patients with Chronic Rhinosinusitis [PDF]
Clinical and Experimental Otorhinolaryngology, 2021 Objectives. This study was conducted to determine whether patients with allergic rhinitis might be more susceptible to human rhinovirus (HRV) infection and whether the effects of infection on the elicited immune responses are different in allergic and ...

B7-H1–expressing antigen-presenting cells mediate polarization of protumorigenic Th22 subsets [PDF]
Journal of Clinical Investigation, 2014 Classical IL-22-producing T helper cells (Th22 cells) mediate inflammatory responses independently of IFN-γ and IL-17; however, nonclassical Th22 cells have been recently identified and coexpress IFN-γ and/or IL-17 along with IL-22. Little is known about how classical and nonclassical Th22 subsets in human diseases are regulated.

Alternative immune checkpoints in immunoregulatory profile of cancer stem cells
Heliyon, 2023 Tumor-mediated bypass of immune checkpoint inhibitor (ICI) therapy with anti-programmed death-1 (PD-1), anti-programmed death-ligand 1 (PD-L1, also called B7–H1 or CD274) or anti-cytotoxic T lymphocyte associated antigen-4 (CTLA-4) is a challenge of ...

B7-H1 blockade increases survival of dysfunctional CD8(+) T cells and confers protection against Leishmania donovani infections. [PDF]
PLoS Pathogens, 2009 Experimental visceral leishmaniasis (VL) represents an exquisite model to study CD8(+) T cell responses in a context of chronic inflammation and antigen persistence, since it is characterized by chronic infection in the spleen and CD8(+) T cells are ...

Expression of programmed cell death ligand-1 and mismatch repair status in endometrial carcinomas
Journal of Mid-Life Health, 2023 Background and Aims: Programmed death ligand-1 (PD-L1) is a co-regulatory molecule that suppresses local immunity, and mismatch repair (MMR) deficiency (dMMR) is reported to influence the response to anti-PD-L1-targeted therapy.
