Article Abstract

The dynamics of the gut mycobiome and its association with cardiometabolic health remain largely unexplored. Here, we employ internal transcribed spacer (ITS) sequencing to capture the gut mycobiome composition and dynamics within a nationwide human cohort of 12,641 Chinese participants, including 1,946 participants with repeated measurements across three years. We find that the gut mycobiome is associated with cardiometabolic diseases and related biomarkers in both cross-sectional and dynamic analyses. Fungal alpha diversity indices and 19 mycobiome genera are the major contributors to the mycobiome-cardiometabolic disease link. Particularly, Saccharomyces emerges as an effect modifier of traditional risk factors in promoting type 2 diabetes risk. Further integration of multi-omics data reveals key metabolites such as γ-linolenic acid and L-valine linking the gut mycobiome to type 2 diabetes. This study advances our understanding of the potential roles of the gut mycobiome in cardiometabolic health.

Human genetic determinants of the gut mycobiome remain uninvestigated despite decades of research highlighting tripartite relationships between gut bacteria, genetic background, and disease. Here, we present the first genome-wide association study on the number and types of human genetic loci influencing gut fungi relative abundance. We detect 148 fungi-associated variants (FAVs) across 7 chromosomes that statistically associate with 9 fungal taxa.

Pediatric-onset Crohn's disease (pCD) is characterized by frequent relapses and long-term impacts on growth, requiring targeted strategies for disease monitoring and treatment. To characterize gut microbiome and mycobiome changes in pCD, we profiled bacterial and fungal communities across multiple gastrointestinal (stool, colon, and terminal ileum) in 30 pre- and post-treatment patients and 36 healthy controls. Microbial shifts in mucosal biopsies lagged behind those in stool, indicating site-specific responsiveness to treatment.

The gut mycobiota, a minor but influential component of the microbiota, is increasingly recognized for its role in shaping host immunity and influencing health. Advances in sequencing technologies have now highlighted the diversity and complexity of these fungal communities. Dysbiosis of the gut mycobiota is associated with various diseases, including inflammatory bowel disease (IBD) and asthma, through mechanisms involving fungal-host interactions, immune modulation, and cross-reactivity.

Background: The phenomenon of urbanization is associated with significant shifts in lifestyle and dietary habits, which can impact the composition of gut microbiota. While variations in gut bacterial communities between rural and urban residents are documented, changes in fungal communities (mycobiota) remain underexplored. This study investigates the impact of urbanization-related dietary shifts on the gut mycobiota in a sub-Saharan African context (Burkina Faso).

Escalating antibiotic resistance of Klebsiella pneumoniae underscores the urgent need for therapeutic strategies. Whereas gut bacterial dysbiosis exacerbates pulmonary infections, the role of gut fungi in modulating lung immunity remains understudied. Here, we demonstrate that antibiotic-induced gut fungal expansion aggravates pneumonia by enhancing alveolar macrophage-driven inflammation via Dectin-1 signaling.
