Autoimmune inflammation

Autoimmune inflammation is a complex pathological process characterized by the immune system's failure to distinguish self from non-self, leading to a persistent attack on the body's own tissues [1]. It is not a single molecular target such as a specific protein or receptor, but rather a systemic state driven by an orchestrated cascade of immune cells—including T-cells, B-cells, and macrophages—and molecular mediators like cytokines and chemokines [2]. In conditions such as rheumatoid arthritis, lupus, and multiple sclerosis, this inflammatory milieu results in chronic tissue destruction, pain, and eventual organ failure [3]. Modern therapeutic strategies focus on inhibiting specific nodes within this inflammatory network, such as tumor necrosis factor (TNF) or Janus kinases (JAK), to restore immune homeostasis [4]. However, because these therapies often suppress broad aspects of the immune system, they carry significant risks, including increased susceptibility to infections and reduced immunosurveillance against tumors [5].

Drugs targeting this process function through various mechanisms including the neutralization of pro-inflammatory cytokines (e.g., TNF-alpha, IL-6, IL-17 blockers), inhibition of intracellular signaling (e.g., JAK inhibitors), depletion of specific immune cell populations (e.g., anti-CD20 for B-cells), or modulation of T-cell costimulation pathways [4].
