Abstract: The present invention relates to a measurement method for complement-dependent bactericidal activity against Streptococcus pneumoniae, and provides a measurement method capable of measuring complement-dependent bactericidal activity against Streptococcus pneumoniae of any capsular serotype. Complement-dependent bactericidal activity against Streptococcus pneumoniae is measured using capsule-deficient Streptococcus pneumoniae, that is, non-encapsulated or substantially non-encapsulated, or transparent Streptococcus pneumoniae. The measurement of the complement-dependent bactericidal activity against Streptococcus pneumoniae of any capsular serotype is enabled.

Abstract: Antibodies (Abs) play roles in protection against influenza. Neutralizing Abs either inhibit the binding of hemagglutinin (HA) to cellular receptors or prevent the conformational change of HA induced by low pH. The former Ab binds to the regions near the sialic acid-binding pocket on the globular head formed by HA1 and generally shows narrow strain specificity. The latter Ab binds to the stem region formed mainly by HA2 and shows broad strain specificity. We isolated a broadly neutralizing Ab against H3N2 viruses. X-ray analysis of the HA/Ab complex indicated that the Ab binds to the valley formed by two neighboring HA monomers at the side of the globular head. The Ab shows neutralizing activity by preventing the conformational change of HA induced at low pH.
Abstract translation: 抗体（Abs）在防止流行性感冒方面发挥作用。 中和抗体可抑制血细胞凝集素（HA）与细胞受体的结合，或阻止由低pH引起的HA的构象变化。 前者Ab与HA1形成的球形头上唾液酸结合口附近的区域结合，通常表现出狭窄的应变特异性。 后者Ab结合主要由HA2形成的茎区，并显示出广泛的应变特异性。 我们分离出一种广泛中和的Ab针对H3N2病毒。 HA / Ab复合物的X射线分析表明，Ab与球状头部侧面的两个相邻的HA单体形成的谷结合。 Ab通过防止在低pH下诱导的HA的构象变化来显示中和活性。

Abstract: A method for producing a retinal pigment epithelial (RPE) cell is disclosed. The method includes promoting a differentiation induction from a pluripotent stem cell into an RPE cell by culturing the pluripotent stem cell in a medium containing an E-cadherin inhibitor. The medium may further contain a differentiation inducer. The pluripotent stem cell may be an embryonic stem(ES) cell or an induced pluripotent stem (iPS) cell.
