Appl Physiol Nutr Metab 2021 Aug 4. Epub 2021 Aug 4.

Thapar Institute of Engineering & Technology, Department of Biotechnology, Delhi , India;

Psoriasis is an inflammatory skin disease. Despite the understanding of the disease pathogenesis, the link between diet-induced inflammation and the risk of psoriasis remains underexplored. Therefore, we have examined the capability of literature-derived Energy-adjusted Dietary Inflammatory Index (E-DII) as a predictive tool for inflammation, incidence, and severity of psoriasis (as indexed by The Psoriasis Area Severity Index (PASI)).

Case Western Reserve University School of Medicine, Department of Dermatology, Cleveland, OH, USA.

Underrepresentation of minorities in clinical research has major implications for equality of access to current treatments in the field of dermatology. To determine whether there has been equitable representation of Black individuals in the clinical trials for dermatologic new molecular entities (NMEs) approved by the US Food and Drug Administration (FDA) since 2015, we analyzed data from the FDA Drug Trials Snapshots program from January 2015 to the present. During this period, there was significant underrepresentation of Black people in the clinical trials for NMEs treating acne vulgaris, plaque psoriasis, actinic keratosis, and squamous cell carcinoma.

High serum level of interleukin-6 is linked with dyslipidemia in oral lichen planus.

Exp Ther Med 2021 Sep 13;22(3):987. Epub 2021 Jul 13.

Department of Pathophysiology, 'Grigore T. Popa' University of Medicine and Pharmacy, 700115 Iasi, Romania.

Oral lichen planus (OLP) is a complex chronic inflammatory disorder in which autocytotoxic CD8 T cells, locally present in the affected tissue, induce basal keratinocyte apoptosis, through the release of several cytokines, such as interleukin-6 (IL-6). IL-6 is a proinflammatory cytokine that is related to alterations in lipid metabolism in psoriasis patients. Impaired lipid metabolism together with high serum levels of triglycerides have been found in association with OLP. Read More

Importance of lymphocyte-stromal cell interactions in autoimmune and inflammatory rheumatic diseases.

Nat Rev Rheumatol 2021 Aug 3. Epub 2021 Aug 3.

Immunogenomics and Inflammation Research Unit, University of Lyon, Department of Immunology and Rheumatology, Hospital Edouard Herriot, Lyon, France.

Interactions between lymphocytes and stromal cells have an important role in immune cell development and responses. During inflammation, stromal cells contribute to inflammation, from induction to chronicity or resolution, through direct cell interactions and through the secretion of pro-inflammatory and anti-inflammatory mediators. Stromal cells are imprinted with tissue-specific phenotypes and contribute to site-specific lymphocyte recruitment. Read More
