Autoimmune Disease and Cancer as Disorders of Regulatory Coherence: A Systems-Level Perspective

This manuscript proposes a novel conceptual framework for understanding autoimmune disease and cancer as disorders of regulatory coherence within immune control systems. Traditionally viewed as separate pathologies—autoimmunity as the result of inappropriate immune activation and cancer as a failure of immune surveillance—this work suggests that both conditions share underlying mechanisms rooted in the breakdown of multiscale regulatory networks. By employing a systems biology perspective, this framework integrates immune signaling, metabolic state, neuroendocrine modulation, and tissue-level feedback to highlight how instability across these interacting layers can precipitate disease. Specifically, autoimmune diseases are conceptualized as failures of global regulatory alignment, leading to persistent self-directed immune activity, while cancer is seen as a breakdown in immune surveillance, permitting tumor evasion. The manuscript addresses longstanding clinical paradoxes observed in both diseases, including relapsing-remitting dynamics, stress-triggered transitions, and the heterogeneous responses to targeted interventions. By framing immune-mediated diseases through the lens of regulatory coherence, this work provides a unifying theoretical scaffold for future experimental and therapeutic research, situating traditional molecular mechanisms within a broader, integrated regulatory architecture.
