Upregulation of Cathepsin S Expression Contributes to Neuronal Damage Following Kainic Acid-Induced Status Epilepticus.

Status epilepticus (SE) is a life-threatening neurological emergency characterized by persistent seizures, leading to brain damage that increases the risk of recurrent seizures due to abnormal electrical impulses produced by damaged neurons. However, the molecular mechanism by which convulsive SE leads to neuronal damage is not completely understood. Cathepsin S (Ctss), a lysosomal cysteine protease, has been implicated in secondary injury after traumatic brain injury.

An integrated map of HIV-human protein complexes that facilitate viral infection.

Recent proteomic and genetic studies have aimed to identify a complete network of interactions between HIV and human proteins and genes. This HIV-human interaction network provides invaluable information as to how HIV exploits the host machinery and can be used as a starting point for further functional analyses. We integrated this network with complementary datasets of protein function and interaction to nominate human protein complexes with likely roles in viral infection.
