Zika Virus Neuropathogenesis-Research and Understanding

Area of Science:

• Neuroscience
• Virology
• Cell Biology

Background:

• Zika virus (ZIKV), a flavivirus, is linked to severe neurological conditions like microcephaly and Guillain-Barré Syndrome.
• ZIKV infects both neuronal and non-neuronal cells, leading to distinct physiological changes and disease impacts.

Purpose of the Study:

• To review the ZIKV life cycle, cellular targets, and mechanisms of neuropathogenesis.
• To discuss current research approaches and knowledge gaps in ZIKV neuropathology.

Main Methods:

• Review of existing literature on ZIKV infection and neuropathogenesis.
• Analysis of cellular responses to ZIKV across various cell types.
• Examination of different ZIKV infection models.

Main Results:

• ZIKV infection induces neuronal apoptosis through mechanisms like cell cycle dysregulation, ER stress, and mitochondrial fragmentation.
• These pathways activate p53-mediated intrinsic cell death.
• Diverse cell types exhibit unique responses to ZIKV infection.

Conclusions:

• ZIKV neuropathogenesis involves complex cellular and molecular mechanisms leading to neuronal death.
• Advanced research models are crucial for understanding ZIKV's impact on the nervous system.
