In the synovial tissues of patients with aseptic loosening after total hip replacement, CD11b was up\u2010regulated, which indicated that CD11b is closely involved in osteolysis around the prosthesis. We found that CD11b, but not CD18, promoted osteoclast (OC) maturation. Here, we show CD11b up\u2010regulated the levels of spleen tyrosine kinase (Syk), c\u2010Fos and nuclear factor of activated T cells, cytoplasmic\u20101 (NFATc1), as well as the activity of extracellular\u2010regulated kinase (Erk), and as a result, osteoclast precursors (OCPs) differentiated and became tartrate\u2010resistant acid phosphatase (TRAP)\u2010positive. In addition, increased tumour necrosis factor\u2010\u03b1 (TNF\u2010\u03b1) induced by ultra\u2010high molecular weight polyethylene (UHMWPE) particles up\u2010regulated the level of CD11b. Taken together, these findings suggest that CD11b is a positive regulator of osteoclastogenesis and that it functions by activating the Syk signalling pathway, while CD18 does not have the same effect.<\/jats:p>","DOI":"10.1111\/jcmm.13254","type":"journal-article","created":{"date-parts":[[2017,6,29]],"date-time":"2017-06-29T10:36:34Z","timestamp":1498732594000},"page":"3445-3452","source":"Crossref","is-referenced-by-count":17,"title":["CD11b
