In mountain gorillas, as in certain human populations, relationships between group members can act as a social buffer, breaking the link between maternal loss, increased social adversity, and decreased fitness.
The absence of helminth parasites in developed countries may be exacerbating pathological, age-associated inflammation, known as inflammaging, suggesting that helminth therapies could provide protection against age-related disease.
Machine learning and experimental tests of receiver bias identify signal components critical to correct species classification in guenons, linking face pattern diversity to selection for species discrimination.
Immune expulsion of helminth parasites is driven by two key pathways mediated by soluble cytokines ligating to the IL-4 and IL-25 receptors acting on innate effector cells throughout the course of infection.
Macrophage dynamics are fundamentally different between two commonly used inbred mouse strains and differences in local resident cell expansion versus monocyte recruitment determine the outcome of tissue nematode infection.
