Hypoxia sensing requires H₂S-dependent persulfidation of olfactory receptor 78 [PDF]

, 2023
Oxygen (O2) sensing by the carotid body is critical for maintaining cardiorespiratory homeostasis during hypoxia. Hydrogen sulfide (H2S) signaling is implicated in carotid body activation by low O2. Here, we show that persulfidation of olfactory receptor

Widespread S-persulfidation in activated macrophages as a protective mechanism against oxidative-inflammatory stress

Redox Biology
Acute inflammatory responses often involve the production of reactive oxygen and nitrogen species by innate immune cells, particularly macrophages. How activated macrophages protect themselves in the face of oxidative-inflammatory stress remains a long ...

Novel roles of sulfur metabolism in stress‐controlled stomata aperture regulation

New Phytologist, Volume 250, Issue 3, Page 1460-1467, May 2026.
Summary Stomatal closure allows plants to conserve water by reducing transpiration during drought. Surprisingly, the assimilation of the macronutrient sulfur is intimately connected to the drought stress response. This Tansley insight will only briefly touch on the general impact of sulfate assimilation on the production of drought‐response metabolites.

Linking Superoxide Production and Scavenging in Plant Development

Plant, Cell &Environment, Volume 49, Issue 4, Page 2048-2068, April 2026.
ABSTRACT Due to their strong oxidizing potential, rapid membrane permeability, and high reactivity, reactive oxygen species (ROS) play essential roles in plant development and stress responses. Superoxide (O2•‐) is a primary product of molecular oxygen reduction and a crucial source of hydrogen peroxide, representing a ROS species of substantial ...

Protein persulfidation in plants : Mechanisms and functions beyond a simple stress response [PDF]

Posttranslational modifications (PTMs) can modulate the activity, localization and interactions of proteins and (re)define their biological function. Understanding how changing environments can alter cellular processes thus requires detailed knowledge ...

Dietary restriction transforms the mammalian protein persulfidome in a tissue-specific and cystathionine γ-lyase-dependent manner

Nature Communications, 2021
Dietary restriction (DR) can increase protein persulfidation but the tissue specificity of this process is not well understood. Here, the authors compare organ-specific protein persulfidomes in young and aged mice under DR, and show that DR-dependent ...

Lifespan‐Extending Endogenous Metabolites

Aging Cell, Volume 25, Issue 2, February 2026.
Endogenous metabolites act as mediators of longevity by modulating conserved cellular pathways. We summarize mechanistic evidence linking specific metabolites to lifespan and healthspan benefits across model systems, with discussion of clinical evidence, translational opportunities, and remaining knowledge gaps.

Polysulfides promote ATF6 oligomerization via persulfidation to modulate ER stress responses

Redox Biochemistry and Chemistry
ATF6 is a UPR sensor regulated by redox modification of luminal cysteine residues. Although polysulfides modulate proteins through cysteine persulfidation, their effect on ATF6 has been unclear.
