The Role of High-Mobility Group Box-1 and Its Crosstalk with Microbiome in Rheumatoid Arthritis

الملخص EN

Rheumatoid arthritis (RA) is a chronic, definitely disabling, and potentially severe autoimmune disease.

Although an increasing number of patients are affected, a key treatment for all patients has not been discovered.

High-mobility group box-1 (HMGB1) is a nuclear protein passively and actively released by almost all cell types after several stimuli.

HMGB1 is involved in RA pathogenesis, but a convincing explanation about its role and possible modulation in RA is still lacking.

Microbiome and its homeostasis are altered in patients with RA, and the microbiota restoration has been proposed to patients with RA.

The purpose of the present review is to analyze the available evidences regarding HMGB1 and microbiome roles in RA and the possible implications of the crosstalk between the nuclear protein and microbiome in understanding and possibly treating patients affected by this harmful condition.
