Potential impact of conjugate vaccine on the incidence of invasive pneumococcal disease among children in Scotland
We sought to determine the potential impact of seven-valent pneumococcal conjugate vaccine on the incidence of invasive pneumococcal disease (IPD) among children in Scotland. Invasive pneumococci from blood and cerebrospinal fluid, isolated between 2000 and 2004 from all children aged less than 5 years in Scotland, were characterized by serotyping. Using reported efficacy data of the seven-valent pneumococcal conjugate vaccine (PCV7) along with likely coverage rates, we made an estimation of the potential impact on the incidence of IPD among children in Scotland. A total of 217 pneumococci were characterized into 22 different serogroups/types, the most common, in rank order, being 14, 19F, 6B, 18C, 23F, 9V, 4, 1, 19A, and 6A. Estimated serotype coverage for PCV7 was 76.5% in those aged less than 5 years of age but increased to 88.9% for those aged 1 year. By using serotype coverage and estimates of vaccine efficacy and uptake, the potential impact of the vaccine for those greater than 2 months of age, but less than 5 years, was estimated as 67.3%, leading to an average of 29 preventable cases per year. The introduction of PCV7 into the childhood immunization schedule would reduce the burden of pneumococcal disease in children, and the incidence would be particularly reduced in those children aged 1 year. Additional benefits may be gained in adults through herd protection. Continued surveillance of IPD is required before, during, and after the introduction of PCV7

Pharmacological chaperone for α-crystallin partially restores transparency in cataract models
Cataracts reduce vision in 50% of individuals over 70 years of age and are a common form of blindness worldwide. Cataracts are caused when damage to the major lens crystallin proteins causes their misfolding and aggregation into insoluble amyloids. Using a thermal stability assay, we identified a class of molecules that bind α-crystallins (cryAA and cryAB) and reversed their aggregation in vitro. The most promising compound improved lens transparency in the R49C cryAA and R120G cryAB mouse models of hereditary cataract. It also partially restored protein solubility in the lenses of aged mice in vivo and in human lenses ex vivo. These findings suggest an approach to treating cataracts by stabilizing α-crystallins
The growing world of small heat shock proteins: from structure to functions.
Small heat shock proteins (sHSPs) are present in all kingdoms of life and play fundamental roles in cell biology. sHSPs are key components of the cellular protein quality control system, acting as the first line of defense against conditions that affect protein homeostasis and proteome stability, from bacteria to plants to humans. sHSPs have the ability to bind to a large subset of substrates and to maintain them in a state competent for refolding or clearance with the assistance of the HSP70 machinery. sHSPs participate in a number of biological processes, from the cell cycle, to cell differentiation, from adaptation to stressful conditions, to apoptosis, and, even, to the transformation of a cell into a malignant state. As a consequence, sHSP malfunction has been implicated in abnormal placental development and preterm deliveries, in the prognosis of several types of cancer, and in the development of neurological diseases. Moreover, mutations in the genes encoding several mammalian sHSPs result in neurological, muscular, or cardiac age-related diseases in humans. Loss of protein homeostasis due to protein aggregation is typical of many age-related neurodegenerative and neuromuscular diseases. In light of the role of sHSPs in the clearance of un/misfolded aggregation-prone substrates, pharmacological modulation of sHSP expression or function and rescue of defective sHSPs represent possible routes to alleviate or cure protein conformation diseases. Here, we report the latest news and views on sHSPs discussed by many of the world's experts in the sHSP field during a dedicated workshop organized in Italy (Bertinoro, CEUB, October 12-15, 2016)
