Modeling the effects of HIV-1 virions and proteins on Fas-induced apoptosis of infected cells
[article]
2007
arXiv
pre-print
Preserved Fulltext
We report a first in modeling and simulation of the effects of the HIV proteins on the (caspase dependent) apoptotic pathway in infected cells. ...
Using the model obtained we have then run the simulations for the infected memory T cells, called also latent T cells, which, at the moment, represent the major obstacle to finding a cure for HIV. ...
In this paper, we focus on simulating the effects on the Fas-induced apoptosis caused by the HIV-1 strand R5 proteins. We report a simulation for the Fas-mediated pathway in HIV-1 infected cells. ...

Human immunodeficiency virus type 1 (HIV-1) infection causes apoptosis of infected CD4 T cells as well as uninfected (bystander) CD4 and CD8 T cells. ...
These data indicate that casp8p41 independently induces apoptosis and is a specific product of HIV-1 protease which may contribute to death of HIV-1-infected cells. ...
