Immunogenicity and safety of an ORF7-deficient skin-attenuated and neuro-attenuated live vaccine for varicella: a randomised, double-blind, controlled, phase 2a trial.

Background: The Oka varicella vaccine strain remains neurovirulent and can establish lifelong latent infection, raising safety concerns about vaccine-related herpes zoster. In this study, we aimed to evaluate the immunogenicity and safety of a skin-attenuated and neuro-attenuated varicella vaccine candidate (v7D vaccine).

Methods: We did this randomised, double-blind, controlled, phase 2a clinical trial in Jiangsu, China.

NFATc3 deficiency protects against high fat diet (HFD)-induced hypothalamus inflammation and apoptosis via p38 and JNK suppression.

Hypothalamic inflammation and apoptosis cause neural injury, playing an important role in metabolic syndrome development. Nuclear Factors of Activated T cells (NFATc3) show many physiological and pathological effects. However, the function of NFATc3 in high fat diet (HFD)-induced hypothalamus injury remains unknown.
