Despite the success of programmed cell death-1 (PD-1) and PD-1 ligand (PD-L1) inhibitors in treating solid tumors, only a proportion of patients respond. Here, we describe a first-in-class bifunctional therapeutic molecule, STAR0602, that comprises an antibody targeting germline Vβ6 and Vβ10 T cell receptors (TCRs) fused to human interleukin-2 (IL-2) and simultaneously engages a nonclonal mode of TCR activation with costimulation to promote activation and expansion of αβ T cell subsets expressing distinct variable β (Vβ) TCR chains. In solution, STAR0602 binds IL-2 receptors in cis with Vβ6/Vβ10 TCRs on the same T cell, promoting expansion of human Vβ6 and Vβ10 CD4 and CD8 T cells that acquire an atypical central memory phenotype.

Takotsubo syndrome (TTS), also known as the transient left ventricular apical ballooning syndrome, is in contemporary times known as novel acute cardiac syndrome. It is characterized by transient left ventricular apical akinesis and hyperkinesis of the basal left ventricular portions. Although the precise etiology of TTS is unknown, events like the sudden release of stress hormones, such as the catecholamines and the increased inflammatory status might be plausible causes leading to the cardiovascular pathologies.

Background: Clusterin is related to immunity and inflammation via regulation of complement activation and bidirectional regulation, and by major proinflammatory cytokines. Clusterin levels have been the subject of a few research both in patients with hyperlipidemia and those with chronic spontaneous urticaria (CSU) separately. The aims of this study were to evaluate the levels of clusterin levels and serum lipids and the relationships between them in patients with CSU.

Aim: Vitamin D, which has immunomodulatory effect, can reduce risk of infections and concentrations of pro-inflammatory cytokines. The aim of this study was to investigate the relationship between the levels of vitamin D and severity of COVID-19.

Methods: A total of 204 patients with COVID-19 disease were enrolled in the study.
