Methane and Inflammation - A Review (Fight Fire with Fire)

Area of Science:

• Microbiology
• Biochemistry
• Pharmacology

Background:

• Mammalian methanogenesis typically indicates gut flora carbohydrate fermentation.
• Methane was historically considered biologically inactive after production or release.
• Emerging evidence suggests methane possesses bioactivity in various in vivo contexts.

Purpose of the Study:

• To review the latest findings on exogenous methane's organ-protective effects.
• To emphasize methane's versatile effects in sepsis models.
• To explore methane's influence on cellular stress responses.

Main Methods:

• Review of recent experimental studies on methane administration.
• Analysis of in vivo models including ischemia/reperfusion, endotoxemia, and sepsis.
• Investigation of methane's impact on oxidative and nitrosative stress pathways.

Main Results:

• Exogenous methane administration demonstrates anti-inflammatory effects.
• Methane exhibits neuroprotective properties in experimental conditions.
• Methane influences key regulatory mechanisms in oxidative and nitrosative stress responses.

Conclusions:

• Methane is biologically active and offers multi-faceted organ protection.
• Exogenous methane shows significant therapeutic potential, especially in sepsis.
• Methane's effects on cellular signaling pathways warrant further investigation.
