Behavior of solutions to equation (2). (A) Both the cell population and the amount of interleukin reach a stable equilibrium (see SM2). (B) A reduction in the rate of interleukin production results in a new equilibrium with a reduced carrying capacity (K′) (C) Homeostatic proliferation of T cells. A drop in the number of cells is compensated by the homeostatic proliferation of the remaining cells, which takes the system back to its original equilibrium. The values of the parameters used in A (in suitable units) are: k = 100, c = 50, λ = 8, φ = 105, μ = 10. In B and C the value of φ changes to 8 ⋅ 104.
