Gut microbiota from patients with COVID-19 cause alterations in mice that resemble post-COVID symptoms.

Long-term sequelae of coronavirus disease (COVID)-19 are frequent and of major concern. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection affects the host gut microbiota, which is linked to disease severity in patients with COVID-19. Here, we report that the gut microbiota of post-COVID subjects had a remarkable predominance of strains with an antibiotic-resistant phenotype compared to healthy controls.

Pericytes are heterogeneous in their origin within the same tissue.

Pericytes heterogeneity is based on their morphology, distribution, and markers. It is well known that pericytes from different organs may have distinct embryonic sources. Yamazaki et al.
