The cytokine interleukin-2 (IL-2) is a critical regulator of immune responses, with an especially well-characterized role in regulating T-cell homeostasis. IL-2 signaling involves three distinct receptor subunits: the IL-2Rα (CD25), IL-2Rβ, and IL-2Rγ. The intracellular transduction of IL-2-induced signals is strictly dependent on IL-2Rβ and IL-2Rγ, while the IL-2Rα is not directly involved in signaling.

In this work, we present a temperature-dependent reaction kinetic study of the water-soluble photobase actinoquinol, in the presence and absence of succinimide, a weak acid reaction partner. We study the temperature dependence of the reaction and connect the observed dynamics to the reaction's thermodynamics.

Background: Ensuring equitable physical access to SARS-CoV-2 testing has proven to be crucial for controlling the COVID-19 epidemic, especially in countries like Nepal with its challenging terrain. During the second wave of the pandemic in May 2021, there was immense pressure to expand the laboratory network in Nepal to ensure calibration of epidemic response. The expansion led to an increase in the number of testing facilities from 69 laboratories in May 2021 to 89 laboratories by November 2021.
