Nipah Virus Pathogenesis

What is Nipah Virus Pathogenesis?
Nipah virus pathogenesis studies the molecular mechanisms by which Nipah virus (NiV) enters host cells, replicates, evades immunity, and causes neuroinvasion, particularly via endothelial tropism and blood-brain barrier disruption.
NiV, a henipavirus, targets respiratory and central nervous systems, leading to high-fatality encephalitis in humans. Key research examines olfactory entry routes in hamsters (Munster et al., 2012, 126 citations) and blood-brain barrier disruption (Al-Obaidi et al., 2018, 126 citations). Over 10 listed papers since 2012 explore genetic determinants and cell-specific infections.
Why It Matters
Understanding NiV pathogenesis enables antiviral development against this zoonotic pathogen with 40-75% fatality rates and pandemic potential from fruit bat reservoirs. Munster et al. (2012) revealed rapid olfactory CNS entry in hamsters, informing outbreak models. Al-Obaidi et al. (2018) showed blood-brain barrier disruption as vital for neurotropism, guiding therapies. Yun et al. (2014) identified budding and fusion differences from Hendra virus, aiding vaccine design.
Key Research Challenges
Blood-brain barrier penetration
NiV disrupts the blood-brain barrier via astrocytes and endothelial cells to access the CNS. Al-Obaidi et al. (2018) demonstrated this as a vital neurotropic property. Exact molecular triggers remain unclear.
Olfactory neuroinvasion route
NiV enters hamster CNS rapidly via olfactory neurons, but human pathways need validation. Munster et al. (2012) mapped spatio-temporal entry. Species differences complicate extrapolation.
Immune cell tropism mechanisms
NiV infects dendritic cells and monocytes, enhancing transendothelial migration to brain. Tiong et al. (2018) showed increased migration across brain microvascular cells. Host evasion strategies require further genetic dissection.
