SPA14 liposomes combining saponin with fully synthetic TLR4 agonist provide adjuvanticity to hCMV vaccine candidate.

In the aim of designing and developing a novel saponin-based adjuvant system, we combined the QS21 saponin with low microgram amounts of the fully synthetic TLR4 agonist, E6020, in cholesterol-containing liposomes. The resulting adjuvant system, termed SPA14, appeared as a long-term stable and homogeneous suspension of mostly unilamellar and a few multilamellar vesicles, with an average hydrodynamic diameter of 93 nm, when formulated in citrate buffer at pH 6.0-6.

Dynamics of communication on measles vaccination on digital platforms in the Brazilian context: challenges and perspectives.

The infodemic and the spread of disinformation have fostered mistrust in vaccines, health institutions, and governments, contributing to a global decline in vaccination coverage and the resurgence of vaccine-preventable diseases like measles. In recent years, the use of digital platforms to access health information, including vaccines, has increased significantly. However, the rapid dissemination of disinformation on these under-regulated platforms can greatly influence vaccination behavior.

Identifying CD19-targeted CAR-T cell immune pathways in an in vitro human immune mimetic cytokine release assay.

CD19-targeted chimeric antigen receptor-modified T (CAR-T) cells have shown success in clinical studies, with several CD19 CAR-T cell products now having been approved for market use. However, this cell therapy can be associated with side effects such as cytokine release syndrome (CRS). Therefore, pre-clinical test systems are highly desired to permit the evaluation of these unwanted effects before clinical trials begin.

The effectiveness of vaccines against COVID-19 in Mexico: A time series approach.

Objective: To estimate the effectiveness of several vaccine brands-Pfizer, Astra, and Sinovac-against symptomatic COVID-19 without information on vaccination at the individual level.

Methods: We use data of mass vaccination programs-specifically, for sexagenarians and quinquagenarians-in three large municipalities of Mexico (Monterrey, Guadalupe, and San Nicolás) to conduct a two-step time series estimation procedure involving a synthetic control group. The data covers the period between the first week of March 2020 and the first week of October 2021.

Developmentally regulated generation of a systemic signal for long-lasting defence priming in tomato.

Tomato is a major global crop. However, its production is limited by Botrytis cinerea. Due to the toxicity of postharvest pesticide application, alternative control methods such as priming are being investigated.
