Actively regulated immune memory differentiation, with a preference for cross-reactive receptors with moderate affinity against pathogens as opposed to high-affinity receptors, confers a long-term benefit to the host.

Resident dermal Mφ are programmed locally, independently of bone-marrow monocytes during Staphylococcus aureus infection, leading to transiently increased resistance, which is limited by a decrease in macrophage life span.

Bacterial CRISPR immunity tracks phage mutations, creating immune diversity in bacterial populations that parallels phage genetic diversity and patterns of phage evolution that are determined by the type and degree of immune cross-reactivity in the CRISPR system.

Inhibition of the integrated stress response restores neuronal and immune dysfunction and alleviates memory deficits in aged mice.

Enriched dietary SFAs, specifically palmitic acid (PA), induce a broad and long-lived innate immune memory response which is harmful during disease exacerbated by inflammation, but beneficial for pathogen clearance.

Sepsis leads to lasting changes in the composition of the pre-existing memory CD8 T cell compartment leading to altered localization, changes in their transcriptional landscape and chromatin accessibility, differential function, and reduced capacity to control infection.

Naïve CD8⁺ T cells are dysregulated during chronic hepatitis C (HCV) infection, and this is reversible after viral clearance.

Unveiling a mechanism for the fate decision of B-cell differentiation into two functionally distinct memory B cell subsets.

Inflamasomme inhibition prevents immune activation, HIV-1 pathogenesis and the splenic content of HIV-1 total DNA in humanized mice when administrated early after HIV-1 infection.

Androgen receptor activation modifies B cell frequencies and functionality, accompanied by weight gain in female mice exposed to human PCOS IgG, highlighting the unrecognized involvement of B cells in PCOS autoimmune comorbidities despite their absence not preventing PCOS phenotype development.
