Macrophage activation syndrome is a severe, ... The hallmark clinical and laboratory features include high fever, hepatosplenomegaly, lymphadenopathy, ...
In rheumatic diseases, this syndrome is more often referred to as macrophage activation syndrome (MAS) and occurs most frequently in the juvenile onset and adult onset forms of Still's disease and in systemic lupus erythematosus. It occurs rarely in juvenile idiopathic arthritis, juvenile Kawasaki disease, and rheumatoid arthritis. [7]
[62] [63] [64] The single-gene (also termed monogenic) causes of cSLE (or a cSLE-like disorder) develop in individuals before they reach 18 years of age. cSLE typically is more severe and potentially lethal than adult-onset SLE because it often involves SLE-induced neurologic disease, renal failure, and/or the macrophage activation syndrome.

A macrophage-activating factor (MAF) is a lymphokine or other receptor based signal that primes macrophages towards cytotoxicity to tumors, cytokine secretion, or clearance of pathogens. Similar molecules may cause development of an inhibitory, regulatory phenotype.
Macrophage activation syndrome, a potentially life-threatening complication of several chronic rheumatic diseases of childhood; The G protein-coupled receptor Mas, a critical part of the renin–angiotensin–aldosterone system (RAAS), encoded by the proto-oncogene MAS1; Mandibular advancement splint, a device used to treat sleep apnea
Mregs can even arise following stress responses. Activation of the hypothalamic-pituitary-adrenal axis leads to production of glucocorticoids that cause decreased production of IL-12 by macrophages. [13] Many cell types including monocytes, M1, and M2 can in a specific microenvironment differentiate to Mregs. [7]

The excess of adipose tissue found in obese patients is found to cause chronic inflammation with an increase in the number of activated macrophages. Subsequently, AIF1 may be an accurate indicator of macrophage activation in the body. [16] There is also evidence that AIF1 could be a marker for diabetic nephropathy when detected in serum. [17]
