NFAT5-Mediated Signalling Pathways in Viral Infection and Cardiovascular Dysfunction

Area of Science:

• Cellular stress response
• Molecular signaling
• Cardiovascular research

Background:

• Nuclear factor of activated T cells 5 (NFAT5) is a transcription factor sensitive to osmotic stress.
• NFAT5 also responds to non-hypertonic stimuli like heat shock, ischemia, and infection.
• Dysregulation of NFAT5 can lead to various pathological conditions.

Purpose of the Study:

• To review NFAT5-mediated signal transduction pathways.
• To discuss stimuli that regulate NFAT5 expression, including non-osmotic factors and epigenetic modifications.
• To highlight emerging research on NFAT5 in cardiovascular diseases.

Main Methods:

• Literature review of NFAT5 signaling and regulation.
• Analysis of NFAT5's role in response to diverse cellular stresses.
• Examination of NFAT5's involvement in disease pathogenesis, particularly cardiovascular conditions.

Main Results:

• NFAT5 activation and nuclear accumulation confer protection against various detrimental effects.
• NFAT5 expression is regulated by osmotic and non-osmotic stimuli, including miRNAs and lncRNAs.
• NFAT5's role in cardiovascular diseases is an expanding area of research.

Conclusions:

• NFAT5 is a crucial stress-responsive factor with dual protective and pathogenic roles.
• Understanding NFAT5 signaling is key to deciphering its involvement in disease.
• Further research into NFAT5's cardiovascular functions is warranted.
