Cancer Immunotherapy Based on the Bidirectional Reprogramming of the Tumor Microenvironment by a “Brakes Off/ Step on the Accelerator” Core‐Shell Manganese Phosphate/siPD‐L1 Modulator

Exploration, EarlyView.
To enhance the comprehensive treatment effect of triple‐negative breast cancer, a pH‐responsive core‐shell manganese phosphate nano‐regulator was prepared to reprogram the tumor microenvironment bi‐directionally. (1) “Brakes off”: Using siPD‐L1 to inhibit PD‐L1 expression to restore CD8+ T cell function.

Nanotherapy in Joints: Increasing Endogenous Hyaluronan Production by Delivering Hyaluronan Synthase 2 [PDF]

Advanced Materials, 2019
AbstractOsteoarthritis (OA) is a common joint degenerative disease that causes pain, joint damage, and dysfunction. External hyaluronic acid (HA) supplement is a common method for the management of osteoarthritis which requires multi‐injections. It is demonstrated that biodegradable mesoporous silica nanoparticles successfully deliver an enzyme ...

Cyclic phosphatidic acid and lysophosphatidic acid induce hyaluronic acid synthesis via CREB transcription factor regulation in human skin fibroblasts [PDF]

, 2014
Cyclic phosphatidic acid (cPA) is a naturally occurring phospholipid mediator and an analog of the growth factor-like phospholipid lysophosphatidic acid (LPA). cPA has a unique cyclic phosphate ring at the sn-2 and sn-3 positions of its glycerol backbone.

Inhibition of hyaluronan synthesis reduces versican and fibronectin levels in trabecular meshwork cells. [PDF]

PLoS ONE, 2012
Hyaluronan (HA) is a major component of the extracellular matrix (ECM) and is synthesized by three HA synthases (HAS). Similarities between the HAS2 knockout mouse and the hdf mutant mouse, which has a mutation in the versican gene, suggest that HA and ...

Nanomaterials for promoting axon regeneration after spinal cord injury: Mechanisms and prospects

Interdisciplinary Medicine, EarlyView.
The effects of clinical therapies for spinal cord injury (SCI) are greatly limited due to poor axon regeneration. This review systematically discusses the ability of nanomaterials (NMs) to treat SCI and the mechanism underlying their therapeutic effects. The properties of NMs that are conducive to axon regeneration after SCI are outlined.

Regulation of Hyaluronan (HA) Metabolism Mediated by HYBID (Hyaluronan-binding Protein Involved in HA Depolymerization, KIAA1199) and HA Synthases in Growth Factor-stimulated Fibroblasts*

Journal of Biological Chemistry, 2015
Regulation of hyaluronan (HA) synthesis and degradation is essential to maintenance of extracellular matrix homeostasis. We recently reported that HYBID (HYaluronan-Binding protein Involved in hyaluronan Depolymerization), also called KIAA1199, plays a ...
