H₂S-based therapies for ischaemic stroke: opportunities and challenges

Area of Science:

• Neuroscience
• Biochemistry
• Pharmacology

Background:

• Stroke is a leading cause of death and disability with limited treatment options.
• Hydrogen sulfide (H2S) is an endogenous signaling molecule with crucial roles in the central nervous system.
• Preclinical studies suggest H2S influences stroke outcomes.

Purpose of the Study:

• To review current research on endogenous and exogenous H2S in stroke pathology.
• To evaluate the therapeutic potential of H2S for ischemic stroke.
• To identify barriers to clinical translation of H2S-based stroke therapies.

Main Methods:

• Literature review of recent studies on H2S and stroke.
• Analysis of data from animal and cellular models of stroke.
• Discussion of clinical translation challenges for H2S therapies.

Main Results:

• H2S, both endogenous and from donors, affects stroke pathology in preclinical settings.
• Evidence supports the neuroprotective effects of H2S in models of cerebral ischemia.
• Significant hurdles remain for the clinical application of H2S-based treatments.

Conclusions:

• H2S-based therapies represent a promising avenue for treating ischemic stroke.
• Overcoming current challenges is essential for successful clinical translation.
• Further research is needed to fully realize the therapeutic potential of H2S in stroke.
