Differential Expression of Proteins Involved in Skin Barrier Maintenance and Vitamin D Metabolism in Atopic Dermatitis: A Cross-Sectional, Exploratory Study.

Atopic dermatitis (AD) is a chronic inflammatory skin disorder influenced by proteins involved in skin barrier maintenance and vitamin D metabolism. Using an intra-patient design, this study compared protein expression in intra-lesional (IL) and peri-lesional (PL) skin biopsies from AD patients and examined associations between protein levels, vitamin D status, and clinical features. Forty-four biopsies from twenty-two AD patients were analyzed using antibody microarrays targeting twelve proteins.

Association between Vitamin D Receptor Polymorphisms, Tight Junction Proteins and Clinical Features of Adult Patients with Atopic Dermatitis.

Introduction: Few studies have explored the intricate connections between vitamin D receptor (VDR) gene polymorphisms, VDR, tight junction (TJ) protein expression and clinical features of atopic dermatitis (AD).

Methods: From 43 adult AD patients, VDR polymorphisms were genotyped from peripheral blood samples using polymerase chain reaction-restriction fragment length polymorphism. VDR, occludin, claudin-1 and ZO-1 protein expression from skin lesion biopsies were assessed by immunohistochemistry.

Plasma Biomarker Profile and Clinical Correlations in Adult Patients With Tuberous Sclerosis Complex.

Objectives: Different pathophysiologic mechanisms, especially involving astrocytes, could contribute to tuberous sclerosis complex (TSC). We assessed neurodegeneration and astrocytopathy plasma biomarkers in adult patients with TSC to define TSC biomarker profile and investigate clinical-radiologic correlations.

Methods: Patients with TSC aged 15 years or older followed at Policlinico "Umberto I" of Rome were consecutively enrolled (July 2021-June 2022).

Syphilis: a mini review of the history, epidemiology and focus on microbiota.

Syphilis is a chronic systemic infectious disease caused by the spirochaete bacterium Treponema pallidum(syphilis treponeme). In recent decades there has been a drastic increase in cases of syphilis,with a relative increase in scientific interest in this regard. However, the data concerning the studyof microbiota in syphilis are few and very scattered.
