LAMP2 and polyarteritis nodosa: Among the subsets of VAS-HTN, the levels of serum anti-LAMP-2 antibody were remarkably increased in all VAS-HTN subsets compared with HC (AAV vs. HC: (107.90 ± 41.13) vs. (55.21 ± 25.09) ng/ml, P < 0.001; PAN vs. HC: (154.34 ± 54.65) vs. (55.21 ± 25.09) ng/ml, P < 0.001; TA vs. HC: (94.98 ± 54.65) vs. (55.21 ± 25.09) ng/ml, P=0.016) (Figure 3(d)).
