T cell immunotherapy success is dependent on effective levels of antigen receptor expressed at the surface of engineered cells. Efforts to optimize surface expression in T cell receptor (TCR)-based therapeutic approaches include optimization of cellular engineering methods and coding sequences, and reducing the likelihood of exogenous TCR α and β chains mispairing with the endogenous TCR chains. Approaches to promote correct human TCR chain pairing include constant region mutations to create an additional disulfide bond between the two chains, full murinization of the constant region of the TCR α and β sequences, and a minimal set of murine mutations to the TCR α and β constant regions.

Although electrochemical biosensors have been developed to detect multiple microRNAs (miRNAs) simultaneously through loading different capture probes, high surface-induced perturbation and competition among probes have reduced the detection sensitivity. To address these challenges, a trefoil DNA capture probe (TDCP) was designed for microRNA-21 (miR-21) and microRNA-16 (miR-16) detection simultaneously. The TDCP exhibits a stable structure, low spatial resistance, and integral rigidity, which decreases high surface-induced perturbations and competition to improve the accessibility of the target miRNA.

The FSH-FSHR pathway has been considered an essential regulator in reproductive development and fertility. But there has been emerging evidence of FSHR expression in extragonadal organs. This poses new questions and long-term debates regarding the physiological role of the FSH-FSHR, and underscores the need for reliable, in vivo analysis of FSHR expression in animal models.

Background: Eating disorders are frequently linked to protein-energy malnutrition, resulting from chronic energy intake reduction, and leading to reduced body weight and altered body composition. A nutritional approach based on the supplementation with a mixture of essential amino acids has proven effective in conditions characterized by reduced dietary intake and increased degradation of endogenous proteins and might also contribute to correct the amino acid deficiency possibly involved in the pathogenesis of eating disorders.
Objective: This study aimed to explore the effects of amino acid supplementation in conjunction with a standard psycho-nutritional rehabilitation program on body composition, symptoms and psychopathology status in 30 female patients with eating disorders hospitalized at the Residenza Palazzo Francisci in Todi, Italy.
Metabolic rewiring in skin epidermis drives tolerance to oncogenic mutations.

Skin epithelial stem cells correct aberrancies induced by oncogenic mutations. Oncogenes invoke different strategies of epithelial tolerance; while wild-type cells outcompete β-catenin-gain-of-function (βcatGOF) cells, Hras cells outcompete wild-type cells. Here we ask how metabolic states change as wild-type stem cells interface with mutant cells and drive different cell-competition outcomes.
