Fusion of E14 chicken parabronchi! Green staining with DSHB 7D6 for L-CAM/E-cadherin stains the lung epithelium. Magenta stains for smooth muscle actin that constricts the developing parabronchi. This was imaged on a confocal microscope and is an MIP. #ShowYourWork #SeenWithDSHB #Figure1
An image of the chicken parabronchi highlighting the interplay between smooth muscle and the epithelium during embryonic lung development. The muscle constricts the epithelium, causing it to outpocket. These outpockets will form the future gas exchange regions in the adult chicken. Green stains for DSHB 7D6 for L-CAM/E-cadherin to stain the lung epithelium. Magenta stains for smooth muscle actin that constricts the developing parabronchi.

A sensory epithelium in the utricle, a balance organ that senses linear head movements & gravity. Rising from the epithelium surface are mechano-sensory bundles made of actin-rich filaments ("stereocilia", stained green), each one with a non-motile primary cilium ("kinocilium", stained magenta). The intercellular junctions of the epithelial cells are stained blue.

Very excited to share this finding from my postdoctoral work that is now published in #ScienceAdvances. We show how the gut’s epithelium modifies enteric behaviors during nutritional adversity via distinct peptidergic signaling axes.

Gut epithelium modifies enteric behaviors during nutritional adversity via distinct peptidergic signaling axes

scRNA-seq reveals persistent aberrant differentiation of nasal epithelium driven by TNFα and TGFβ in post-COVID syndrome

Screenshot from latest Science for ME weekly update

#LongCovid #PASC
scRNA-seq reveals persistent aberrant differentiation of nasal epithelium driven by TNFα and TGFβ in post-COVID syndrome — Reddy et al. "Here, we show that a severe post-COVID syndrome (PCS) phenotype is characterized by immune-mediated damage to the nasal epithelium, occurring independently of viral persistence." "in severe PCS, basal proliferating cells feature a TGFβ-driven response, with myeloid cells maintaining an inflammatory profile. This inflammation is triggered through MIF and propagated by TNFα signaling"
