Krüppel-Like Factors Modulate Susceptibility To Neuropsychiatric Disorders.

Area of Science:

• Neuroscience
• Molecular Biology
• Genetics

Background:

• Krüppel-like factors (KLFs) are transcription factors regulating gene expression.
• KLFs are vital for cell growth, differentiation, proliferation, and development.
• Specific KLFs (KLF4, KLF6, KLF7, KLF9, KLF10) are key in central nervous system (CNS) development and maturation.

Purpose of the Study:

• To review experimental evidence on molecular and cellular pathways activated by KLFs in neurodevelopment.
• To describe the role of KLFs in maintaining blood-brain barrier (BBB) integrity.
• To elucidate the connection between KLFs, BBB integrity, neuroinflammation, and neuropsychiatric disorders.

Main Methods:

• Review of experimental evidence from preclinical models.
• Integration of clinical data to understand KLF contributions.
• Analysis of molecular and cellular pathways involving KLFs in neurodevelopment and brain function.

Main Results:

• KLFs (KLF4, KLF6, KLF7, KLF9, KLF10) are essential for neurogenesis and neural differentiation in the CNS.
• KLFs influence brain function by supporting BBB integrity and modulating neuroinflammation.
• Defects in KLF2, KLF4, KLF6, KLF9, and KLF14 compromise BBB integrity and exacerbate neuroinflammation, disrupting brain function.

Conclusions:

• KLFs play a critical role in neurodevelopment and maintaining brain function.
• Disruptions in KLF function, BBB integrity, and neuroinflammation are implicated in neuropsychiatric disorders.
• Further research integrating preclinical and clinical data is needed to fully understand KLF crosstalk in neuropsychiatric conditions.
