It has been postulated that the acquired immune deficiency syndrome (AIDS) may be a result of the systemic presence of an immunosuppressive cyclosporine-like molecule released in chronic fungal infections. This possibility was examined by analysis of blood, plasma, or serum samples obtained from AIDS patients, from subjects with prodromal AIDS, and from healthy subjects belonging to several of the recognized "AIDS risk groups" for cyclosporine-like substances. The sensitivity of the analytic methods and the stability of cyclosporine during the storage of blood were verified by analysis of blood specimens obtained from a normal volunteer after oral ingestion of various doses of cyclosporine. Radioimmunoassay, high-pressure liquid chromatography, and analysis by combination of these two methods failed to detect cyclosporine or cyclosporine-like substances in subjects with established or prodromal AIDS and in AIDS-free persons belonging to the risk groups. These results indicate that the breakdown of cellular immunity in AIDS is not due to circulating cyclosporine.

Pemphigus vulgaris is a rare autoimmune blistering disorder which can occur with other disorder with autoimmune etiology like lichen planus pigmentosus. The concurrence of pemphigus vulgaris and HIV infection has been rarely reported in literature. Here we report a 31 year old patient who came with oral and skin erosions suggestive of pemphigus vulgaris and later developed HIV infection with lichen planus pigmentosus.

The hemostatic system prevents and stops bleeding, maintaining circulatory integrity after injury. It directly interacts with the complement system, which is key to innate immunity. In coronavirus disease 2019 (COVID-19), dysregulation of the hemostatic and complement systems has been associated with several complications.

Background: The causes of breast cancer are poorly understood. A potential risk factor is Epstein-Barr virus (EBV), a lifelong infection nearly everyone acquires. EBV-transformed human mammary cells accelerate breast cancer when transplanted into immunosuppressed mice, but the virus can disappear as malignant cells reproduce.

Cerebral accumulation of alpha-synuclein (αSyn) aggregates is the hallmark event in a group of neurodegenerative diseases-collectively called synucleinopathies-which include Parkinson's disease, dementia with Lewy bodies and multiple system atrophy. Currently, these are diagnosed by their clinical symptoms and definitively confirmed postmortem by the presence of αSyn deposits in the brain. Here, we summarize the drawbacks of the current clinical definition of synucleinopathies and outline the rationale for moving toward an earlier, biology-anchored definition of these disorders, with or without the presence of clinical symptoms.

Hepatocellular carcinoma (HCC), the most common primary liver cancer, is a highly aggressive malignancy with limited viable therapeutic options. For early HCC, resection surgery is currently the most effective treatment. However, in advanced stages, resection alone does not sufficiently address the disease, so finding a method with a better prognosis is necessary.
