Research Spotlight – March 2022

The March edition of Research Spotlight presents 10 recent publications from scientists whom Boster has served.

In this edition, scientists discussed how a better understanding of the PD-L1 expression regulation can be pivotal in achieving better clinical outcomes in EBV-infected cancer patients. Another research study proposed a self-powered smart patch that serves as a reservoir of chemokine-/neural-directing exosomes, offering a serviceable strategy to stimulate skin neuro-engineering and regeneration of tissues and organs.

In terms of bone diseases, one paper revealed the potential role of Calca, an osteoblast-derived ProCT in the bone microenvironment that is required to limit bone resorption during iPTH. Several development strategies in the fields of nanotechnology and biomaterials were also achieved through the construction of cell-responsive peptide assemblies and nanorod-like coating with ions doping.

Authors: Wang, J., Ge, J., Wang, Y., Xiong, F., Guo, J., Jiang, X., Zhang, L…
Journal: Nature Communications

Epstein-Barr virus (EBV) is reportedly the first identified human tumor virus, and is closely related to the occurrence and development of nasopharyngeal carcinoma (NPC), gastric carcinoma (GC), and several lymphomas. PD-L1 expression is elevated in EBV-positive NPC and GC tissues; however, the specific mechanisms underlying the EBV-...

Journal: Signal Transduction and Targeted Therapy

Interleukin-3 (IL-3) is a hematopoietic growth factor and critical regulator of inflammatory response such as sepsis. IL-3 binds to IL-3 receptor α (IL-3Rα), which is then associated with IL-3Rβ to initiate signaling. How IL-3-triggered physiological and pathological effects are regulated at the receptor level is unclear. Here, we...

Procalcitonin is Expressed in Osteoblasts and Limits Bone Resorption Through Inhibition of Macrophage Migration During Intermittent PTH Treatment

Authors: Baranowsky, A., Jahn, D., Jiang, S., Yorgan, T., Ludewig, P...
Journal: Bone Research

Intermittent injections of parathyroid hormone (iPTH) are applied clinically to stimulate bone formation by osteoblasts, although continuous elevation of parathyroid hormone (PTH) primarily results in increased bone resorption. Here, we identified Calca, encoding the sepsis biomarker procalcitonin (ProCT), as a novel target gene of...

Authors: Yu, D., Li, B., Yu, M., Guo, S., Guo, Z., Han, Y.
Journal: Bioactive Materials

The dissolution-derived release of bioactive ions from ceramic coatings on metallic implants, despite improving osseointegration, renders a concern on the interfacial breakdown of the metal/coating/bone system during long-term service. Consequently, persistent efforts to seek alternative strategies instead of dissolution-derived...

Journal: Biomaterials

Skin wound is always accompanied with nerve destruction. Due to the limited clinical treatment option, loss of skin sensation with unsatisfactory nerve regeneration is remained to be a challenge for wound therapy. Endogenous mesenchymal stem cells (MSCs) based in situ regeneration, of which, MSCs recruited by chemokines and directed...
