Abstract Matching of symmetry at interfaces is a fundamental obstacle in molecular assembly. Virus-like particles (VLPs) are important platforms to generate vaccines against pathogenic threats including Covid-19. However, symmetry mismatch between multimeric antigens and VLP subunits can prohibit vaccine nanoassembly. Here we explore spontaneous amidation to establish principles for coupling VLPs to diverse antigen symmetries. SpyTag003/SpyCatcher003-mediated decoration enabled efficient VLP conjugation and extreme thermal resilience. Many people showed pre-existing antibodies to SpyTag:SpyCatcher, but decreased a...

Credit: United Nations Office for Disaster Risk Reduction (UNDRR)By Lawrence SurendraBANGKOK, Thailand, Aug 24 2020 (IPS) The COVID 19 Pandemic continues relentlessly. Deaths approaching a million globally, 22 million infected and growing. Brazil, India, the US and Russia accounting for almost 50% of the total cases in the world. Medically the promise of a vaccine is given as signs of hope; what surprises awaits us when such a vaccine is available, would be another story. Economically, to address the uncertainty and the grim future ahead, the UN, some governments and even Joe Biden the US Presidential hopeful, are waving ...

In this study, we demonstrated that immunization with CspZ-YA, a CspZ mutant protein with no FH-binding activity, protected mice from infection by several spirochete genotypes introduced via tick feeding. We found that the sera from CspZ-YA-vaccinated mice more efficiently eliminated spirochetes and blocked CspZ FH-binding activity than sera from CspZ-immunized mice. We also found that vaccination with CspZ, but not CspZ-YA, triggered the production of anti-FH antibodies, justifying CspZ-YA as an LD vaccine candidate. The mechanistic and efficacy information derived from this study provides insights into the development of...

Abstract Leptospira interrogans, Borrelia burgdorferi, and Treponema pallidum are important pathogenic spirochetes. The incidence of human diseases caused by pathogenic spirochetes, e.g., leptospirosis, Lyme disease, and syphilis, has been recently increasing, posing a threat to public health. Mechanisms of spirochete pathogenicity are not yet fully understood, and no safe and effective vaccine to prevent and control the infection by pathogenic spirochetes is currently available.In this article, we review the progress of research into the pathogenic spirochete vaccine, mainly in terms of vaccine types.The developm...

In conclusion, taller body height at the entry to adulthood, supposed to be a marker of early-life environment, is associated with lower risk of dementia diagnosis later in life. The association persisted when adjusted for educational level and intelligence test scores in young adulthood, suggesting that height is not just acting as an indicator of cognitive reserve. A Comparison of Biological Age Measurement Approaches https://www.fightaging.org/archives/2020/02/a-comparison-of-biological-age-measurement-approaches/ Researchers here assess the performance of a range of approaches to measuring biological...
