Osteoclasts are multinucleated, giant cells derived from my.loid progenitors. While receptor activator of NF-κB ligand(RANKL)stimulation is the primary.driver of osteoclast differentiation, additional signaling further contributes to osteoclast ***, we demonstrate that immunoglobulin superfamily.member 11(Ig SF11), whose expression increases during osteoclast differentiation, regulates osteoclast differentiation through interaction with postsy.aptic density.protein 95(PSD-95), a scaffold protein with multiple protein interaction domains. Ig SF11 deficiency.in vivo results in impaired osteoclast differentiation and bone resorption but no observed defect in bone formation. Consequently. Ig SF11-deficient mice exhibit increased bone *** in vitro osteoclast culture sy.tems, we show that Ig SF11 functions through homophilic interactions. Additionally. we demonstrate that impaired osteoclast differentiation in Ig SF11-deficient cells is rescued by.full-length Ig SF11 and that the Ig SF11-PSD-95 interaction requires the 75 C-terminal amino acids of Ig SF11. Our findings reveal a critical role for Ig SF11 during osteoclast differentiation and suggest a role for Ig SF11 in a receptor-and signal transduction molecule-containing protein complex.

Three different series of lead-free ceramics,i.e.,(1-y.Bi1.03(1_x)LaxFeO_(3)-y.aTiO_(3)(y.0.27,x=0.00-0.12),(y.0.30,x=0.00-0.10),and(y.0.33,x=0.00-0.08)are prepared via a conventional solid-state reaction with water *** X-ray.diffraction and electrical property.measurements,two morphotropic phase boundaries(MPBs)are discovered in all three ceramic *** first MPB(MPB-Ⅰ)appeared between rhombohedral and tetragonal phases,whereas the second MPB(MPB-Ⅱ)appeared between tetragonal and cubic-like *** highest direct piezoelectric coefficients(d_(33)=201,274,and 268 pC/N)are mainly.attributed to the ty.ical MPB-I of the rhombohedral and tetragonal ***,the highest converse piezoelectric coefficients(d_(33*)=490,500,and 570 pm/V with Curie temperature>330℃)are obtained for compositions near to the MPB-II.A significant enhancement in the dielectric constant at low temperature is associated with the local structural heterogeneity.by.La^(3+)doping,which serves as an origin for a high piezoelectric strain *** on the cry.tal structure as well as on the dielectric,ferroelectric,and piezoelectric properties,a phase diagram is constructed for La-doped BiFeO3-BaTiO3 *** phase diagram reveals the relationship between piezoelectric performance and cry.tal structure.
