System-wide cellular and immune environment

The system-wide cellular and immune environment refers to the integrated network of immune cells, signaling molecules, and physiological conditions that maintain organismal homeostasis and coordinate responses to pathological challenges (Spitzer and Nolan, 2017, Cell). It encompasses the systemic distribution and activity of leukocytes, cytokines, and chemokines across various tissues and the circulatory system. In the context of disease, particularly oncology, the systemic immune environment can be reprogrammed by tumors to facilitate immune evasion and promote progression (Hiam-Galvez et al., 2021, Nature Reviews Cancer). Because this term describes a broad biological context or state rather than a discrete protein, enzyme, or receptor, it is not considered a specific therapeutic target. Instead, pharmacological interventions typically target individual components within this environment, such as checkpoint receptors or specific cytokines, to modulate the overall immune landscape for therapeutic benefit.
