The expression level of a microglia marker (CD11b) was detected by immunofluorescence. The mRNA and protein expression levels of BGN and Toll-like receptor 2 (TLR2) were determined by quantitative RT-PCR and western blotting. BGN was upregulated in activated microglial cells. Knockdown of BGN efficiently attenuated β-amyloid-induced microglial activation and expressions of proinflammatory factors. Furthermore, the present findings provided evidence showing that BGN could regulate β-amyloid-induced microglial activation through TLR2 in BV2 cells. Our results suggested that TLR2 signaling may be involved in the regulatory role of BGN in β-amyloid-induced microglial activation. Our results suggested that TLR2 signaling may be involved in the regulatory role of BGN in β-amyloid-induced microglial activation. One of the most aggressive microorganisms in infective endocarditis (IE) is Staphylococcus aureus. We analyse the resistance of S. aureus to antibiotics and its impact on the clinical course of IE in a recent 15-year period. Retrospective study of patients with IE in a university hospital from 2005 to 2019. Bivariate and multivariate analysis of severity at admission, comorbidities, minimum inhibitory concentrations (MIC) and mortality. Of the 293 IE cases, 66 (22.5%) were due to S. aureus, and 21 (7.2%) were methicillin-resistant S. aureus (MRSA). The prevalence of strains with a MIC to vancomycin ≥ 1mg/L increased from 4.8% to 63.6% (p <0.001) and the cases of MRSA from 38 to 27.3% (p = 0.045). Older age (p= 0.02), comorbidity (p <0.01) and nosohusial origin (p = 0.01), were factors associated with MRSA. But the antimicrobial resistance and severity on admission were not associated with exitus; predictive factors were the right-sided IE (OR = 0.08; 95% CI 0.01-0.51), comorbidities (OR per Charlson index point = 1.30; 95% CI 1.01-1.69)
