Local identifiability of a HIV-1 infection model using a sensitivity approach
João Gonçalo Silva Marques,

Abstract:
The dynamic modeling of the Human Immunodeficiency Virus 1 (HIV-1) infection is still one of the great challenges in systems biology. The high prevalence of Acquired Immune Deficiency Syndrome (AIDS), known to be caused by HIV, and the fact that no cure has yet been discovered, confers relevancy to this area of study. In this paper, a dynamic model for the HIV-1 infection is analyzed. The sensitivity and identifiability issues are addressed with the purpose of optimizing the time points at which patients’ blood samples should be drawn. This paper shows that there are time periods far more informative than others, thus improving parameter identifiability and estimability in the reverse engineering step.

Upcoming Events
Workshop “Metabolism and mathematical models: Two for a tango” – 2nd Edition
Title: Workshop Metabolism and mathematical models: Two for a tango – 2nd Edition
Dates: October 25-26, 2022
Location: This workshop will be held in a virtual way
The topic of this workshop is metabolism in general, with a special focus, although not exclusive, on parasitology. Besides an exploration of the biological, biochemical and biomedical aspects, the workshop will also aim at presenting some of the mathematical modelling, algorithmic theory and software development that have become crucial to explore such aspects.
This workshop is being organised in the context of two projects, both with the Inria European Team Erable. One of the projects involves a partnership with the University of São Paulo (USP), in São Paulo, Brazil, more specifically the Institute of Mathematics and Statistics (IME) and the Institute of Biomedical Sciences – Inria Associated Team Capoeira – and the other involves the Inesc-ID/IST in Portugal, ETH in Zürich and EMBL in Heidelberg – H2020 Twinning Project Olissipo.
The workshop is open to all members of these two projects but also, importantly, to the community in general.
The program and more details are available here.
