Photoisomerization detected in a fully wavelength‐tunable rhodopsin mimic system

Acta Crystallographica Section D, Volume 82, Issue 6, Page 664-671, June 2026.
The mechanism of retinal photoswitching is illuminated in a designed rhodopsin mimic. Two mechanisms, a conventional cis–trans isomerization and an unprecedented `photodehydration', are observed at atomic resolution in single crystals.We describe the photoisomerization of the retinylidene protonated Schiff base in human retinol‐binding protein II ...

Widespread Variation in Retinochrome Spectral Absorbance Across Scallop Phylogeny

Molecular Ecology, Volume 35, Issue 11, June 2026.
ABSTRACT Vision is a two‐step process, including phototransduction initiated by a retinal‐bound opsin photopigment, and subsequent photopigment regeneration wherein the inactive state is restored. Because retinal isomerization, or changing of the molecular structural conformation, drives the activation of opsin photopigments, the reverse process is a ...

Estrogen receptor β regulates sex‐dependent airway mechanics and inflammation in a murine model of allergen exposure

Physiological Reports, Volume 14, Issue 11, June 2026.
Abstract Sex differences in asthma severity have been reported; however, the specific contribution of estrogen receptor β (ERβ) remains incompletely defined. We tested the hypothesis that ERβ modulates sex‐specific physiological responses to chronic allergen exposure using C57BL/6J wild‐type (WT) and ERβ‐deficient (Esr2−/−) male and female mice ...

Isolation and functional characterization of primary human proximal tubular epithelial cells from brain‐dead organ donors

Physiological Reports, Volume 14, Issue 11, June 2026.
Protocol for isolation and culture of primary proximal tubular epithelial cells from kidneys retrieved from brain‐dead organ donors and designated for research after rejection for transplantation. These cells, bbd‐PTEC, express canonical proximal tubule epithelial markers and demonstrate functional transport.

Neuregulin‐1 Mitigates Kidney Injury in Humanized Sickle Cell Mice

The FASEB Journal, Volume 40, Issue 10, 31 May 2026.
Compared with untreated sickle cell (HbSS) mice, neuregulin‐1 (NRG‐1) treatment reduced plasma heme, lactate dehydrogenase, and pro‐inflammatory cytokines while increasing the proportion of circulating F‐cells. NRG‐1 improved urinary biomarkers of kidney health, decreasing cystatin C and NGAL levels and increased renal repair markers clusterin and ...
