AI Article Synopsis

  • The increasing production and demand for nano-black phosphorus (nano-BPs) materials raise concerns about their potential environmental leakage and human exposure through various pathways.
  • This Review highlights the inconsistent toxicological findings related to nano-BPs, which result from differences in their properties, testing methods, and cell types studied.
  • The article discusses important biological responses to nano-BPs, including cellular uptake, modes of cell death, and immunological effects, while also identifying challenges in assessing their health risks and suggesting broader applications for these nanomaterials.

Article Abstract

The production scalability and increasing demand for nano-black phosphorus materials (nano-BPs) inevitably lead to their environmental leakage, thereby raising the risk of human exposure through inhalation, ingestion, dermal, and even intravenous pathways. Consequently, a systematic evaluation of their potential impacts on human health is necessary. This Review outlines recent progress in the understanding of various biological responses to nano-BPs. Attention is particularly given to the inconsistent toxicological findings caused by a wide variation of nano-BPs' physicochemical properties, toxicological testing methods, and cell types examined in each study. Additionally, cellular uptake and intracellular trafficking, cell death modes, immunological effects, and other biologically relevant processes are discussed in detail, providing evidence for the potential health implications of nano-BPs. Finally, we address the remaining challenges related to the health risk evaluation of nano-BPs and propose a broader range of applications for these promising nanomaterials.

The lack of an in-vivo pathology marker for synuclein pathology has been a long standing challenge for dementia for Lewy bodies (DLB) research. This issue is critically important for phase II trials, which are often small, requiring the precise measurement of the biological effects, whether disease modifying or symptomatic. Recent advances have enabled the determination of alpha-synuclein pathology status with CSF measurements, using aggregation assays [RT-QUIC].

Background: Developing drugs for treating Alzheimer's disease (AD) has been extremely challenging and costly due to limited knowledge on underlying biological mechanisms and therapeutic targets. Repurposing drugs or their combination has shown potential in accelerating drug development due to the reduced drug toxicity while targeting multiple pathologies.

Method: To address the challenge in AD drug development, we developed a multi-task machine learning pipeline to integrate a comprehensive knowledge graph on biological/pharmacological interactions and multi-level evidence on drug efficacy, to identify repurposable drugs and their combination candidates RESULT: Using the drug embedding from the heterogeneous graph representation model, we ranked drug candidates based on evidence from post-treatment transcriptomic patterns, mechanistic efficacy in preclinical models, population-based treatment effect, and Phase 2/3 clinical trials.

Background: Understanding the fundamental differences between the human and pre-human brain is a prerequisite for designing meaningful models and therapies for AD. Expressed CHRFAM7A, a human restricted gene with carrier frequency of 75% in the human population predicts profound translational significance.

Method: The physiological role of CHRFAM7A in human brain is explored using multiomics approach on 600 post mortem human brain tissue samples (ROSMAP).

Background: Reliable treatment approaches for addressing early cognitive impairment and Alzheimer's disease (AD) are currently lacking. Given the multifactorial nature of AD, therapeutic strategies need to focus on disease-specific biochemical pathways. Given the significance of metabolic pathways in cognitive impairment, it is essential to investigate alternative disease modifiers capable of targeting multiple metabolic pathways, such as phytochemicals.

Background: Chronic innate neuroinflammation mediated by microglia and astrocytes in response to Aβ and pathological Tau species is a cardinal feature of AD that contributes to disease pathogenesis. Accumulating evidence now also highlight an instrumental role of T cells and peripheral-central immune crosstalk in the pathophysiology of AD. Both preclinical and clinical reports suggest the potential therapeutic interest of peripheral immunomodulatory approaches aimed at amplifying regulatory T cells (Tregs), e.
