“…Single-cell mass cytometry CyTOF (PLT Tech., China) staining was performed following a previously published method. 46 Cells were washed with 1× PBS once and then stained with 100 μL of 250 nM cisplatin (Fluidigm, USA) for 5 min on ice to exclude dead cells, and then incubated in Fc receptor blocking solution before stained with surface antibodies cocktail for 30 min on ice. Cells were washed with FACS buffer (1xPBS + 0.5%BSA) for twice and fixed in 200 μL of intercalation solution (Maxpar Fix and Perm Buffer containing 250 nM 191/193Ir, Fluidigm, USA) overnight.…”

The knee joint has long been considered a closed system. The pathological effects of joint diseases on distant organs have not been investigated. Herein, our clinical data showed that post-traumatic joint damage, combined with joint bleeding (hemarthrosis), exhibits a worse liver function compared with healthy control. With mouse model, hemarthrosis induces both cartilage degeneration and remote liver damage. Next, we found that hemarthrosis induces the upregulation in ratio and differentiation towards Th17 cells of CD4+ T cells in peripheral blood and spleen. Deletion of CD4+ T cells reverses hemarthrosis-induced liver damage. Degeneration of cartilage matrix induced by hemarthrosis upregulates serological type II collagen (COL II), which activates CD4+ T cells. Systemic application of a COL II antibody blocks the activation. Furthermore, bulk RNAseq and single-cell qPCR analysis revealed that the cartilage Akt pathway is inhibited by blood treatment. Intra-articular application of Akt activator blocks the cartilage degeneration and thus protects against the liver impairment in mouse and pig models. Taken together, our study revealed a pathological joint–liver axis mediated by matrikine-activated CD4+ T cells, which refreshes the organ-crosstalk axis and provides a new treatment target for hemarthrosis-related disease.

“…However, additional work examining the toxicity and long-term tissue effects is important. Recent studies are starting to tease out the effects shape, size, and crystal surface structures have on tissue responses. − With the addition of drugs within CaPPs, a more systematic understanding of these tissue responses is critical as the field starts to move toward clinical translation.…”

Calcium Phosphate Delivery Systems for Regeneration and Biomineralization of Mineralized Tissues of the Craniofacial Complex

et al. 2023

Calcium phosphate (CaP)-based materials have been extensively used for mineralized tissues in the craniofacial complex. Owing to their excellent biocompatibility, biodegradability, and inherent osteoconductive nature, their use as delivery systems for drugs and bioactive factors has several advantages. Of the three mineralized tissues in the craniofacial complex (bone, dentin, and enamel), only bone and dentin have some regenerative properties that can diminish due to disease and severe injuries. Therefore, targeting these regenerative tissues with CaP delivery systems carrying relevant drugs, morphogenic factors, and ions is imperative to improve tissue health in the mineralized tissue engineering field. In this review, the use of CaP-based microparticles, nanoparticles, and polymer-induced liquid precursor (PILPs) amorphous CaP nanodroplets for delivery to craniofacial bone and dentin are discussed. The use of these various form factors to obtain either a high local concentration of cargo at the macroscale and/or to deliver cargos precisely to nanoscale structures is also described. Finally, perspectives on the field using these CaP materials and next steps for the future delivery to the craniofacial complex are presented.

“…Biosafety is an important parameter for assessing the applicability of these multiepitope nanovaccines. [43] To determine the biosafety of multiepitope nanovaccines, the body weights of the mice were monitored during and after vaccination; no statistically differences were observed the in body weights of the multiepitope nanovaccine-immunized mice and PBS-immunized mice throughout the experiment. Two weeks after the final immunization, the major organs were collected from the immunized mice and subjected to histological analysis through H&E staining.…”

Seasonal influenza vaccines typically provide strain‐specific protection and are reformulated annually, which is a complex and time‐consuming process. Multiepitope vaccines, combining multiple conserved antigenic epitopes from a pathogen, can trigger more robust, diverse, and effective immune responses, providing a potential solution. However, their practical application is hindered by low immunogenicity and short‐term effectiveness. In this study, multiple linear epitopes from the conserved stem domain of hemagglutinin and the ectodomain of matrix protein 2 are combined with the Helicobacter pylori ferritin, a stable self‐assembled nanoplatform, to develop an influenza multiepitope nanovaccine, named MHF. MHF is prokaryotically expressed in a soluble form and self‐assembles into uniform nanoparticles. The subcutaneous immunization of mice with adjuvanted MHF induces cross‐reactive neutralizing antibodies, antibody‐dependent cell‐mediated cytotoxicity, and cellular immunity, offering complete protection against H3N2 as well as partial protection against H1N1. Importantly, the vaccine cargo delivered by ferritin triggers epitope‐specific memory B‐cell responses, with antibody level persisting for over 6 months post‐immunization. These findings indicate that self‐assembled multiepitope nanovaccines elicit potent and long‐lasting immune responses while significantly reducing the risk of vaccine escape mutants, and offer greater practicality in terms of scalable manufacturing and genetic manipulability, presenting a promising and effective strategy for future vaccine development.
