Autoimmune diseases are usually accompanied by tissue injury caused by autoantigen-specific T-cells. KV1.3 channels participate in modulating calcium signaling to induce T-cell proliferation, immune activation and cytokine production. Effector memory T (TEM)-cells, which play major roles in many autoimmune diseases, are controlled by blocking KV1.3 channels on the membrane. Toxins derived from animal venoms have been found to selectively target a variety of ion channels, including KV1.3. By blocking the KV1.3 channel, these toxins are able to suppress the activation and proliferation of TEM cells and may improve TEM cell-mediated autoimmune diseases, such as multiple sclerosis and type I diabetes mellitus.

Second Department of Neurology, Attikon University Hospital, National & Kapodistrian University of Athens, Athens, Greece.
Introduction: The current literature on the prevalence and potential association between disease-modifying therapies (DMTs) and cancer risk in the MS population has yielded mixed findings.
Methods: This study aimed to estimate cancer prevalence and cancer risk in patients with MS (PwMS) under prolonged DMT exposure. Database search include: MEDLINE PUBMED, SCOPUS, and Google Scholar.
Contextualization of Diabetes: A Review of Reviews from Organisation for Economic Co-operation and Development (OECD) Countries.
Curr Diab Rep

Centre for Surveillance and Applied Research, Health Promotion and Chronic Disease Prevention Branch, Public Health Agency of Canada, 785 Carling Ave, Ottawa, Ontario, K1A 0K9, Canada.
Purpose Of Review: The prevalence of diabetes is rising around the world and represents an important public health concern. Unlike individual-level risk and protective factors related to the etiology of diabetes, contextual risk factors have been much less studied. Identification of contextual factors related to the risk of type 1 and type 2 diabetes in Organisation for Economic Co-operation and Development (OECD) countries may help health professionals, researchers, and policymakers to improve surveillance, develop policies and programs, and allocate funding.

Pemphigus vulgaris (PV) is a group of autoimmune bullous diseases characterized by life-threatening intradermal blisters. Hashimoto thyroiditis (HT) is a kind of autoimmune disease with abnormal increase of thyroid peroxidase autoantibody (TPOAb), which is the thyroid specific antibody, leading to hypothyroidism. In recent years, the probability of HT in patients with PV is increasing, and the co-disease may be related to the effect of TPOAb autoantibody on oral keratinocytes.

Objective: The duration of viral shedding and criteria for de-isolation in the hospital among immunocompromised patients with coronavirus disease 2019 (COVID-19) remain unclear. This study aimed to evaluate viral shedding duration in immunocompromised patients infected with the Omicron variant of severe acute respiratory syndrome coronavirus 2.
Methods: A prospective cohort study was performed at 2 tertiary medical centers in Japan during the Omicron epidemic waves from July 2022 to January 2023.
Aculeanoids A-D, the second 17-nor fusicoccane diterpenoids with immunosuppressive activity from Aspergillus aculeatus.
Phytochemistry

Hubei Key Laboratory of Natural Medicinal Chemistry and Resource Evaluation, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430030, PR China. Electronic address:
Chemical investigation on the secondary metabolites of Aspergillus aculeatus led to the identification of ten modified fusicoccane-type diterpenoids aculeanoids A-J (1-10). Their structures and absolute configurations were characterized by comprehensive spectroscopic analysis, DP4+ analysis, Mo(OAc)-induced ECD, single-crystal X-ray diffractions, and ECD calculations. Compounds 1-4 belong to a rare class of 17-nor fusicoccane diterpenoids, with only one previously reported example.
