Coronavirus-induced disease-2019 (COVID-19) continues to cause significant morbidity and mortality worldwide. While studies on SARS-CoV-2 effects on immune cell function continue to progress, we know very little about the significance of depletion of key immune effectors by the virus in the mortality and morbidity of the disease. This commentary outlines what is the reported literature thus far on the effect of virus on NK cells known to kill virally infected cells. It also underscores the necessity for the future comprehensive studies of NK cells in SARS-CoV-2 infected individuals and animal models to better understand the role and significance of reported NK cell depletion and functional inactivation in disease morbidity and mortality, in hope to design effective therapeutic interventions for the disease.

Introduction Recently, immune cells within the tumor microenvironment (TME) have become crucial in regulating cancer progression and treatment responses. The dynamic interactions between tumors and immune cells are emerging as a promising strategy to activate the host's immune system against various cancers. The development and progression of hepatocellular carcinoma (HCC) involve complex biological processes, with the role of the TME and tumor phenotypes still not fully understood.

Purpose Of Review: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease, characterized by hepatic steatosis with at least one cardiometabolic risk factor. Patients with MASLD are at increased risk for the occurrence of cardiovascular events. Within this review article, we aimed to provide an update on the pathophysiology of MASLD, its interplay with cardiovascular disease, and current treatment strategies.

Background: Immunosuppression might increase the risk of skin cancer in organ transplant recipients (OTRs), with azathioprine (AZA), exerting a fundamental role in the carcinogenesis of those tumors. This systematic review and meta-analysis aims to address the risk of developing malignant skin neoplasms in OTRs undergoing immunosuppression with AZA.
Methods: PubMed, Cochrane and Embase were searched for studies with OTRs who have a treatment regimen involving Azathioprine therapy after transplantation and that analyzed the emergence of skin neoplasia.
