Ariangela J. Kozik studies the respiratory microbiome as it relates to asthma. In this mSphere of Influence article, she reflects on how two papers, "Time's up to adopt a biopsychosocial model to address racial and ethnic disparities in asthma outcomes" (E. C. Matsui, A. S. Adamson, and R. D. Peng, Allergy Clin Immunol 143:2024-2025, 2019, https://doi.org/10.1016/j.jaci.2019.03.015) and "Health disparities and the microbiome" (K. Findley, D. R. Williams, E. A. Grice, and V. L. Bonham, Trends Microbiol 24:847-850, 2016, https://doi.org/10.1016/j.tim.2016.08.001), shape her approach to human microbiome research.

In 2020, I featured two articles in the "mSphere of Influence" commentary series that had profound implications for the field of immunology and helped shape my research perspective. These articles were "Global Analyses of Human Immune Variation Reveal Baseline Predictors of Postvaccination Responses" by Tsang et al. (Cell 157:499-513, 2014, https://doi.

Treatment with antibiotics is a major risk factor for infection, likely due to depletion of the gastrointestinal microbiota. Two microbiota-mediated mechanisms thought to limit colonization include the conversion of conjugated primary bile salts into secondary bile salts toxic to growth and competition between the microbiota and for limiting nutrients. Using a continuous flow model that simulates the nutrient conditions of the distal colon, we investigated how treatment with 6 clinically used antibiotics influenced susceptibility to infection in 12 different microbial communities cultivated from healthy individuals.

Unlabelled: Advances in technology have facilitated extensive sample collection to explore microbiomes across diverse systems, leading to a growing reliance on ultracold freezers for storing both samples and extracted DNA. However, freezer malfunctions can jeopardize data integrity. To evaluate the impact of an unexpected -80°C freezer failure and the recoverability of thawed soil samples, we extracted DNA and compared it to long-term DNA stored at -20°C and original 16S and ITS2 sequencing data collected before the malfunction.

Unlabelled: Myeloid phagocytes are essential for antifungal immunity against pulmonary and systemic infections. However, the molecular mechanisms underlying fungal clearance by phagocytes remain incompletely understood. In this study, we investigated the role of Perforin-2 () in antifungal immunity.

Heat shock factor (HSF)-type regulators are stress-responsive transcription factors widely distributed among eukaryotes, including fungi. They carry a four-stranded winged helix-turn-helix DNA-binding domain considered as the signature domain for HSFs. The genome of the opportunistic yeast encodes four HSF members, namely, Sfl1, Sfl2, Skn7, and the essential regulator, Hsf1.
