Androgenetic alopecia (AGA)-a condition characterized by hair loss due to aging, autoimmune responses, stress, and other factors-results in hair follicle (HF) shrinkage and dermal papilla cell apoptosis. So far, only minoxidil (MXD) and finasteride have been approved for AGA treatment. However, both drugs have serious side effects, including hypersensitivity and sexual dysfunction.

Article Synopsis
  • Parkinson's disease (PD) is increasing globally due to aging, but effective treatments for its motor and cognitive symptoms are still lacking, with neuroinflammation and neuronal apoptosis worsening these conditions.
  • The study developed minocycline-loaded iron oxide nanoparticles (FeO-MIN NPs) that can cross the blood-brain barrier using near-infrared (NIR) irradiation, allowing targeted delivery to the brain.
  • The FeO-MIN NPs showed strong anti-inflammatory and antioxidative properties, protecting neurons and improving motor function and cognitive ability in PD mice, indicating their potential as a therapeutic option.

Article Synopsis
  • The way drugs work depends a lot on how well they are delivered in the body, and bad delivery can cause serious side effects.
  • New technologies are helping create better delivery systems, like using tiny particles (nano DDSs), natural materials (EBDDSs), and even living cells (LCDDSs).
  • Living cell drug delivery systems are exciting for researchers because they work well with the body and can target diseases better, but more research is needed to understand how to use them effectively.

Article Synopsis
  • Alzheimer's disease (AD) is increasingly common due to an aging population, yet effective treatments are still lacking, with current understanding of its mechanisms remaining unclear.
  • The study introduces a black phosphorus nanosheet-based delivery system (BP-MB) that enhances drug delivery across the blood-brain barrier using near-infrared light and shows promise in reversing neuroapoptosis and neuroinflammation critical to AD pathology.
  • In animal tests, BP-MB improved cognitive function and alleviated symptoms of AD by reducing toxic factors and shifting microglia towards a less inflammatory state, showcasing its potential as a novel treatment for the disease.

Communication between tumors and lymph nodes carries substantial significance for antitumor immunotherapy. Remodeling the immune microenvironment of tumor-draining lymph nodes (TdLN) plays a key role in enhancing the anti-tumor ability of immunotherapy. In this study, we constructed a biomimetic artificial lymph node structure composed of F127 hydrogel loading effector memory T (T) cells and PD-1 inhibitors (aPD-1).

Photothermal therapy is favored by cancer researchers due to its advantages such as controllable initiation, direct killing and immune promotion. However, the low enrichment efficiency of photosensitizer in tumor site and the limited effect of single use limits the further development of photothermal therapy. Herein, a photo-responsive multifunctional nanosystem was designed for cancer therapy, in which myeloid-derived suppressor cell (MDSC) membrane vesicle encapsulated decitabine-loaded black phosphorous (BP) nanosheets (BP@ Decitabine @MDSCs, named BDM).

The clinical application of cancer immunotherapy is unsatisfied due to low response rates and systemic immune-related adverse events. Microwave hyperthermia can be used as a synergistic immunotherapy to amplify the antitumor effect. Herein, we designed a Gd-based metal-organic framework (Gd-MOF) nanosystem for MRI-guided thermotherapy and synergistic immunotherapy, which featured high performance in drug loading and tumor tissue penetration.

In recent years, the use of active substances as excipients or as substitutes for other excipients in the design of modern drug delivery systems has received widespread attention, which has promoted the development of the theory of unification of medicines and excipients in the design of traditional Chinese medicine(TCM) preparations. Adopting the theory of unification of medicines and excipients to design drug delivery systems can reduce the use of excipients and thus the cost of preparations, reduce drug toxicity, increase drug solubility and biocompatibility, enhance synergistic effect, and realize targeted delivery and simultaneous delivery of multiple components. However, the research on the application of this theory in the modern drug delivery system of TCM preparations is still insufficient, with few relevant articles.

Oral disease, as a class of diseases with very high morbidity, brings great physical and mental damage to people worldwide. The increasing burden and strain on individuals and society make oral diseases an urgent global health problem. Since the treatment of almost all oral diseases relies on materials, the rapid development of advanced materials and technologies has also promoted innovations in the treatment methods and strategies of oral diseases.

The combination of excessive reactive oxygen species (ROS) levels, neuroinflammation, and pathogenic protein aggregation disrupt the homeostasis of brain microenvironment, creating conditions conducive to the progression of Parkinson's disease (PD). Restoring homeostasis by remodeling the brain microenvironment could reverse this complex pathological progression. However, treatment strategies that can induce this effect are currently unavailable.

Parkinson's disease (PD) is a serious neurodegenerative disease wherein the progressive destruction of dopaminergic neurons results in a series of related movement disorders. Effective oral delivery of anti-Parkinson's drugs is challenging owing to the blood-brain barrier (BBB) and the limited plasma exposure. However, polymeric nanoparticles possess great potential to enhance oral bioavailability, thus improving drug accumulation within the brain.

Parkinson's disease (PD) is the second most common neurodegenerative disease globally, and there is currently no effective treatment for this condition. Excessive accumulation of reactive oxygen species (ROS) and neuroinflammation are major contributors to PD pathogenesis. Herein, ultrasmall nanoscale coordination polymers (NCPs) coordinated by ferric ions and natural product curcumin (Cur) were exploited, showing efficient neuroprotection by scavenging excessive radicals and suppressing neuroinflammation.

The limited clinical response and serious side effect have been challenging in cancer immunotherapy resulting from immunosuppressive tumor microenvironment (TME) and inferior drug targeting. Herein, an active targeting TME nanoplatform capable of revising the immunosuppressive TME microenvironment is designed. Briefly, gold nanorods (GNRs) are covered with silica dioxide (SiO) and then coated manganese dioxide (MnO) to obtain GNRs@SiO@MnO (GSM).

Parkinson's disease (PD), a neurodegenerative disease that shows a high incidence in older individuals, is becoming increasingly prevalent. Unfortunately, there is no clinical cure for PD, and novel anti-PD drugs are therefore urgently required. However, the selective permeability of the blood-brain barrier (BBB) poses a huge challenge in the development of such drugs.
