A model for interactions between immune cells and HIV considering drug treatments

Abstract: In this work we analyze the capacity of the human body to combat HIV. The model here treated takes into consideration four types of defense of an organism infected by HIV: susceptible defense cells, the infected immune cells, killer T cells, and the HIV specific killer T cells. This model therefore analyzes the interactions between the responses of killer T cells and HIV infections, evidencing how the immune system is attacked and how it defends. An optimal control problem is proposed to derive an optimal sequ… Show more

“…Now the finite element method for (33) is: find v ∈ U such that Since the forward (1)-(2) and adjoint (36) problems are nonlinear their solutions can be found by Newton's method. For the discretization the variational formulation of the forward problem (1)-( 2) for all ū ∈ H 1 u (Ω T ) is:…”

“…As escolhas dos valores de u 1 e u 2 foram feitas através de uma função que simula uma distribuição uniforme no intervalo [0, 1], onde 0é a ausência de tratamento e 1é a eficiência máxima do tratamento. Os valores dos demais parâmentros e as condições iniciais usados nas simulações foram retiradas de [5]. 4.…”

“…In Malik et al (2013) one is faced with a study regarding three types of plurivalent vaccines against the human papillomavirus (HPV), which considers distinct dynamics for women and men. Outside pandemic models, optimal control strategies can be used to study drug administration in HIV treatment (PASTORE et al, 2018;ARRUDA et al, 2015). In addition, a variety of optimal control strategies in biological mathematical models can be found in the literature, see for example (FATMAWATI;TASMAN, 2015;HELAL et al, 2015;NANNYONGA et al, 2015;TAI et al, 2015).…”
