The important role of CD8+ T-cells in the pathogenesis of psoriasis is well-determined. However, besides type 1 cytokines that were formerly known, it was recently found that these cells secrete type 17 and type 22 cytokines. The majority of IL-17A+CD8+ T-cells in the blood belong to a subset of innate T-cells named mucosa-associated invariant T-cells (MAIT). However, the majority of IL-17A+CD8+ T-cells in psoriatic epidermis are conventional T-cells and are up-regulated in psoriasis. In contrast to Th17 cells that secrete only IL-17, Tc17 cells secrete IFN- ϒ, TNF-α, CCL20, IL-22, and granzyme B as well. The k...

If you’re like most people, you’ve seen a ton of direct-to-consumer (DTC) drug ads in recent years. They’re all over television, in magazines, online, on billboards, and slapped on the sides of buses, promoting treatments for arthritis, cancer, heartburn, psoriasis, flagging memory — and more. The deluge of drug ads can be overwhelming. Worse, the information is often incomplete, biased, or confusing. That’s why we’re launching the Harvard Health Ad Watch series to highlight some benefits and problems with health product advertisements. We’ll focus on the evidence behind the ads an...

Molecular biomarkers can be powerful tools for aiding in the efficiency and precision of clinical decision-making. Feature selection methods, machine-learning, and biostatistics have been applied to discover subsets of molecular markers that identify target classes of clinical cases. For example, in the field of dermatology, these approaches have been used to develop predictive models that identify skin diseases, ranging from melanoma to psoriasis, based upon a variety of biomarkers. However, a continuous increase in the variety and size of datasets from which candidate biomarkers can be derived, and limitations in the com...

ConclusionsOur data show that KLHTT has anti-neutrophilic inflammatory effects in inhibiting ROS generation and cell adhesion. KLHTT also mitigated NET formation, mainly via an ROS-dependent pathway. In addition, KLHTT reduced neutrophil infiltration and improved the severity of IMQ-induced psoriasis-like skin inflammation in mice. Therefore, KLHTT may prove to be a safe and effective psoriasis therapy in the future.Graphical abstract

Authors: Hooper D Abstract Psoriasis is a common, chronic inflammatory skin disease that can affect any part of the body. It is a highly visible condition with symptoms that include the appearance of red, thick, scaly patches on the arms, legs, trunk, soles of the feet, palms, and nails, but most commonly on the elbows, knees, and scalp.

The safety profile of tildrakizumab was characterized in nonclinical studies using a pharmacologically relevant cynomolgus monkey model. In repeat-dose toxicity studies, cynomolgu...
