TRP channels as critical pathways in temperature-induced asthma

Area of Science:

• Environmental Health
• Molecular Biology
• Respiratory Medicine

Background:

• Epidemiological studies link extreme temperatures and abrupt climate shifts to increased asthma incidence and severity.
• The precise molecular mechanisms connecting temperature variations to asthma pathogenesis are not well understood.
• Transient receptor potential (TRP) channels are implicated in asthma, but research primarily focuses on TRPV1, TRPA1, and TRPV4.

Purpose of the Study:

• To elucidate the molecular mechanisms by which extreme temperatures influence asthma development.
• To investigate the role of TRP channel expression in mediating the effects of temperature on asthma.
• To identify potential therapeutic targets for temperature-related asthma exacerbations.

Main Methods:

• Systematic review of studies indexed in PubMed and Web of Science.
• Analysis of research on TRP channel expression and function in the respiratory system.
• Examination of the relationship between ambient temperature, TRP channel regulation, and asthma.

Main Results:

• Extreme temperatures and abrupt temperature changes are associated with increased asthma incidence and severity.
• TRP channels, particularly TRPA1, TRPV1, and TRPM8, show altered expression in the respiratory system under abnormal temperature conditions.
• Changes in TRP channel expression influence thermal sensing and thermoregulation, indicating a bidirectional interaction.

Conclusions:

• Extreme temperatures promote asthma development through the regulation of TRP channel expression in the respiratory system.
• Understanding the role of TRP channels provides a mechanistic link between ambient temperature and asthma.
• This knowledge can inform the development of novel therapeutic targets and prevention strategies for temperature-sensitive asthma.
