Article Abstract
Polyamidoamines (PAMAMs) are a class of dendrimer with monodispersity and controlled topology, which can deliver biologically active macromolecules (, genes and proteins) to specific regions with high efficiency and minimum side effects. In detail, PAMAMs can be functionalized easily by core modification or surface amendment to encapsulate a wide range of biomacromolecules. Besides, self-assembled, cross-linked and hybrid PAMAMs with customized therapeutic purposes are developed as delivery vehicles, which makes PAMAMs promising for biomacromolecule therapy. In this review, we comprehensively summarize the application of PAMAMs in biomacromolecule delivery from the synthesis of functionalized PAMAM carriers to the development of PAMAM-based drug delivery systems. The underlying strategies for PAMAM functionalization and assembly are first systematically discussed, and then the current applications of PAMAMs for biomacromolecule delivery are reviewed. Finally, a brief perspective on the further applications of PAMAMs concludes, aiming to provide insights into developing PAMAM-based biomacromolecule delivery systems.

Triple-negative breast cancer (TNBC) remains a formidable clinical challenge due to its aggressive behavior, lack of therapeutic targets, and poor prognosis. The PI3K/AKT/mTOR pathway is highly activated in TNBC, making it a promising therapeutic target. Conventional PEGylated nanocarriers often face challenges, such as accelerated blood clearance and lysosomal trapping.

The COVID-19 pandemic has demonstrated the need for rapid, flexible, and readily adaptable treatment options for future pandemic preparedness. Due to the speed at which viruses like SARS-CoV-2 mutate, the customary approach of using highly specific monoclonal antibodies as neutralization therapies is challenging, given their size, production complexity, and cost. Here, we leveraged rational protein design to create fusion proteins from small, antibody-mimetic proteins, Designed Ankyrin Repeat Proteins (DARPins) and a self-assembling hexameric coiled coil (CC-HEX).

Lignin, traditionally considered a low-value byproduct of the pulp and paper industry, has gained significant attention in recent years as a sustainable precursor for the development of functional materials. This paradigm shift is driven by recent studies exploring the structure-property-performance relationships of lignin-based functional materials, which have provided valuable insights for selective chemical functionalization or pretreatment of lignin. Furthermore, the use of complementary analytical techniques has helped to shed light into lignin's complex and heterogeneous structure, opening new avenues for chemical modification.

Development of efficient and stimuli-responsive gene delivery systems for therapeutic protein expression and immunomodulation remains challenging. Here, we report the synthesis of three types of pH-, reactive oxygen species (ROS)- and glutathione (GSH)-responsive dendrimer nanogels (for short, DNGs-pH, DNGs-ROS, and DNGs-GSH, respectively) a microemulsion method for delivery of messenger RNA (mRNA) and plasmid DNA (pDNA), both encoding enhanced green fluorescent protein (for short, mEGFP and pEGFP), to dendritic cells (DCs). The synthesized DNGs exhibit a nanoscale dimension, high monodispersity, desired colloidal stability, low cytotoxicity, and efficient gene delivery efficiency.

Cisplatin resistance remains a major clinical challenge in cancer therapy, often driven by the upregulation of DNA repair pathways. Here, we present a dual-functional nanotherapeutic system (HFn-NERiP-Pt(IV)) combining a glutathione-responsive PROTAC (NERiP) with a ferritin nanocarrier for targeted ERCC1/XPF degradation and enhanced platinum delivery. NERiP selectively degrades ERCC1/XPF upon release in reductive tumor environments, suppressing nucleotide excision repair and enhancing platinum cytotoxicity.
