Elevated levels of cxcl13 have been detected in the blood of IPF patients, with even higher serum concentrations observed in those experiencing non-arterial hypertension or acute exacerbations.[30] Furthermore, cxcl13 has been implicated in numerous inflammatory conditions,[31,32] autoimmune disorders,[33] and malignancies.[34] Its involvement in diverse pathological states suggests that cxcl13 may serve as a promising therapeutic target. This evidence concerns the gene CXCL13 and autoimmune disease.
