DdmDE is a novel plasmid defense system that was discovered in the seventh pandemic Vibrio cholerae strain of the biotype O1 EI Tor. In this issue of Cell, Yang and coworkers reveal the mechanisms underlying the assembly and activation of the DdmDE defense system.

Background: Several studies have shown the influential role of nutraceuticals on cognition and mental functions. Dihydroxytrimethoxyflavone, a natural flavone found in herbal drugs, is documented to be neuroprotective in different model systems. Nevertheless, possible memory improvement effects of dihydroxytrimethoxyflavone via nuclear factor-E2-related factor 2 (Nrf2) (a crucial regulator of antioxidative system) has not been systematically evaluated.

Solenogastres is a group of mollusks with evolutionary and ecological importance. Nevertheless, their diversity is underestimated and knowledge about the distribution of the approximately 300 formally described species is limited. Factors that contribute to this include their small size and frequent misidentification by non-specialists.

Objective: The innate immune defense plays a pivotal role in protecting the urinary tract from uropathogenic invasion and maintaining immune homeostasis. Dysregulation of the innate immune system can result in recurrent urinary tract infections (RUTI) due to heightened susceptibility to uropathogens. Despite this, predicting the risk of recurrence and the degree of immune compromise in patients who have had one urinary tract infection remains challenging.

Our understanding of type 2 immunity has undergone a substantial transformation in recent years, revealing previously unknown functions. Beyond its canonical role in defence against parasitic helminth infections, type 2 immunity safeguards the host through additional mechanisms, including the suppression of excessive type 1 immune responses, regulation of tissue repair and maintenance of adipose tissue homeostasis. However, unlike type 1 immune responses, type 2 immunity is perceived as a potential promoter of tumorigenesis.

Disease tolerance is an evolutionarily conserved host defense strategy that preserves tissue integrity and physiology without affecting pathogen load. Unlike host resistance, the mechanisms underlying disease tolerance remain poorly understood. In the present study, we investigated whether an adjuvant (β-glucan) can reprogram innate immunity to provide protection against influenza A virus (IAV) infection.
