Excessive, constant inflammation in response to aspects of one's own cellular biochemistry is a feature of both autoimmune disease and aging. While transient inflammation is necessary for effective regeneration and defense against pathogens, constant unresolved inflammatory signaling is destructive to tissue structure and function. It is a major component of the pathology of common age-related conditions. The challenge in addressing this is that unwanted inflammation and desirable inflammation both involve the same molecular signals and points of control. To date, therapies that reduce chronic inflammation do so via crude blockade of signals or mechanisms, with the side effect of reduced immune capability, a reduction in the normal immune response when it is needed. The research community is slowly making progress towards finding points of distinction, however, approaches to intervention that have greater effects on unwanted inflammation than they do on the normal immune response. One such line of work is noted here, focused on autoimmunity.
Current autoimmune disease treatments like hydroxychloroquine work by broadly blocking endosomes, the compartments inside cells where incoming materials are sorted and processed, including molecules that trigger immune responses. While effective, this approach can lead to significant side effects - including gastrointestinal problems and, less commonly, vision damage-causing a significant number of patients to stop treatment.
