In situ detection of individual classical MHC-I gene products in cancer.

Tumor-specific HLA class I expression is required for cytotoxic T-cell elimination of cancer cells expressing tumor-associated or neo-antigens. Cancers downregulate antigen presentation to avoid adaptive immunity. The highly polymorphic nature of the genes encoding these proteins, coupled with quaternary-structure changes after formalin fixation, complicate detection by immunohistochemistry.

Loss of H3K9 trimethylation leads to premature aging.

Aging is the major risk factor for most human diseases and represents a major socio-economical challenge for modern societies. Despite its importance, the process of aging remains poorly understood. Epigenetic dysregulation has been proposed as a key driver of the aging process.

Neurostatus-SMARTCARE clinical trial: Enabling health care professionals to assess EDSS for decentralized trials in multiple sclerosis.

Background: Neurostatus-Expanded Disability Status Scale (EDSS) is the standard measure used to assess impairment and disability in multiple sclerosis (MS) trials but requires trained expert neurologists.

Objectives: This study aims to evaluate the concordance of Neurostatus-EDSS assessments from specially trained health care professionals (HCPs) and standardized trained neurologists.

Methods: A Swiss multicenter, randomized, cross-over study with 100 people with MS.

Daily or Twice Daily Treatment with Topical Steroids Results in Similar Responses in Eosinophilic Esophagitis.

Background & Aims: Few data compare topical corticosteroid (tCS) dosing regimens and outcomes. We aimed to compare treatment outcomes in patients with eosinophilic esophagitis (EoE) by once or twice daily dosing regimens.

Methods: We conducted a retrospective cohort study using the UNC EoE Clinicopathologic Database of newly diagnosed patients with EoE treated with a tCS who had a follow-up endoscopy with biopsy.

Topical Steroids Are Effective and Safe in Patients With Eosinophilic Esophagitis Over a Median of 6.5 Years of Chronic Use.

Goals: To determine long-term efficacy and safety of tCS for treatment of EoE.

Background: Maintenance therapy with topical corticosteroids (tCS) is recommended for eosinophilic esophagitis (EoE), but data for long-term use are still needed.

Study: This retrospective cohort study assessed newly diagnosed patients with EoE who were treated with a tCS and had a follow-up endoscopy with biopsy after at least 5 years.
