Inspecting the interaction between HIV and the immune system through genetic turnover [PDF]

arXiv, 2022
Chronic infections of the human immunodeficiency virus (HIV) create a very complex co-evolutionary process, where the virus tries to escape the continuously adapting host immune system. Quantitative details of this process are largely unknown and could help in disease treatment and vaccine development.

An in-host model of HIV incorporating latent infection and viral mutation [PDF]

Dynamical Systems, Differential Equations and Applications, AIMS Proceedings, 2015 pp. 913-922, 2015
We construct a seven-component model of the in-host dynamics of the Human Immunodeficiency Virus Type-1 (i.e, HIV) that accounts for latent infection and the propensity of viral mutation. A dynamical analysis is conducted and a theorem is presented which characterizes the long time behavior of the model.

Mathematical analysis of an in-host model of viral dynamics with spatial heterogeneity [PDF]

Disc. Cont. Dyn. Sys. B 21: 1237-1257, 2016, 2015
We consider a spatially-heterogeneous generalization of a well-established model for the dynamics of the Human Immunodeficiency Virus-type 1 (HIV) within a susceptible host. The model consists of a nonlinear system of three coupled reaction-diffusion equations with parameters that may vary spatially.

Human immunodeficiency virus transmission at each step of the care continuum in the United States.

JAMA Internal Medicine, 2015
IMPORTANCE Human immunodeficiency virus (HIV) transmission risk is primarily dependent on behavior (sexual and injection drug use) and HIV viral load.

Virus-specific CD8+ cytotoxic T-lymphocyte activity associated with control of viremia in primary human immunodeficiency virus type 1 infection

Journal of Virology, 1994
Human immunodeficiency virus type 1 (HIV-1) Env-, Gag-, Pol-, Nef-, and Tat-specific cytotoxic T-lymphocyte (CTL) activities were quantitated temporally in five patients with symptomatic primary HIV-1 infection.

Treatment with indinavir, zidovudine, and lamivudine in adults with human immunodeficiency virus infection and prior antiretroviral therapy.

New England Journal of Medicine, 1997
BACKGROUND The new protease inhibitors are potent inhibitors of the human immunodeficiency virus (HIV), and in combination with other antiretroviral drugs they may be able to cause profound and sustained suppression of HIV replication.

Safety and practicality of an excisional lymph node study driving HIV cure research in South Africa

Frontiers in Immunology
IntroductionStudying diseased human tissues offers better insights into the intricate interactions between pathogens and the human host. In conditions such as HIV and cancers, where diseases primarily manifest in tissues, peripheral blood studies are ...

The Effects of Latent Infection on the Dynamics of HIV [PDF]

Differential Equations and Dynamical Systems, 3, 2016, 2013
One way in which the human immunodeficiency virus (HIV-1) replicates within a host is by infecting activated CD4+ T-cells, which then produce additional copies of the virus. Even with the introduction of antiretroviral drug therapy, which has been very successful over the past decade, a large obstacle to the complete eradication of the virus is the ...
