In a Ugandan birth cohort, early childhood infection-exposure, notably to malaria, helminths, and diarrhoea, is associated with lower prevalence of atopy and allergy-related diseases in later childhood.
An integrated stem cell-based disease modeling and computational approach demonstrates how proximal airway epithelium is critical for SARS-CoV-2 infectivity and distal alveolar cells are critical for simulating the host responses.
Analyses of detailed clinical and entomological data from cohort studies reveal how anti-parasite and anti-disease immunity against P. falciparum develop as a function of age and transmission intensity.
HLA class I-disease associations have been studied for decades; a new approach for investigating the underlying mechanism can overcome past problems with interpretation and help to understand the etiology of human diseases.
Type I interferon and interferon-γ signaling redundantly protects mice from the tick-borne pathogen Rickettsia parkeri in the skin, and interferon receptor-deficient mice are a tractable model for investigating rickettsiosis.
Tick-derived sequence variation in the fusion glycoprotein of Crimean-Congo hemorrhagic fever virus (CCHFV) drastically impairs infection of mammalian cells, suggesting that certain CCHFV strains undergo purifying selection in mammalian hosts.
