Article Abstract
Platelets have long been acknowledged for their essential roles in hemostasis and thrombosis; however, recent insights highlight their broader involvement as key participants in host responses during infection. Beyond their classical functions, platelets exhibit diverse anti-infective capabilities, such as direct pathogen internalization, receptor-mediated pathogen recognition, the release of antimicrobial peptides, cytokines, and chemokines, and the generation of immunomodulatory extracellular vesicles. These intrinsic platelet attributes enable dynamic interactions with pathogens and immune cells, significantly contributing to pathogen capture, neutralization, and the orchestration of innate and adaptive immune responses. This review examines the multifaceted intrinsic roles of platelets and delineates the beneficial outcomes of their activation, providing an integrated perspective on platelet-driven immunity and defense mechanisms during infection.

During the long course of evolution, fish have developed complex skin structures to adapt to the dynamic aquatic environment. These skin features not only reflect optimal adaptation to the aquatic environment but also play a key role in effectively reducing fluid drag and improving swimming efficiency, to reveal the intrinsic connection between the complex skin structure of fish and drag reduction performance and to provide new design ideas for the drag reduction surface of underwater vehicles. Based on the different drag reduction characteristics of fish skin structures, this paper divides existing biomimetic drag reduction technologies into three categories: riblet drag reduction, flexible drag reduction, and composite drag reduction.

Ferroptosis is a regulated, non-apoptotic form of cell death marked by the accumulation of iron-dependent lipid peroxides. This process causes rapid rupture of the plasma membrane and the release of intracellular contents. Ferroptosis acts as an intrinsic tumor-suppressive mechanism.

Cancer metabolic reprogramming is a fundamental hallmark that enables tumor cells to sustain their malignant behaviors. Beyond its role in supporting growth, invasion, and migration, metabolic rewiring actively contributes to anticancer drug resistance. Cancer cells not only reshape their own metabolism but also engage in aberrant metabolic crosstalk with nonmalignant components within the tumor microenvironment (TME).

Introduction: Oral squamous cell carcinoma (OSCC) has a poor prognosis due to its immunosuppressive tumor microenvironment (TME), in which tumor-associated macrophages (TAMs) play a pivotal role in promoting disease progression and therapeutic resistance. This study examines whether Prussian blue nanoparticles (PB NPs) could reprogram TAMs and block tumor-stroma communication in OSCC.
Methods: PB NPs were synthesized using polyvinylpyrrolidone-assisted coprecipitation and characterized by transmission electron microscopy, dynamic light scattering, and UV-Vis spectroscopy.

Cholangiocarcinoma (CCA) is a fatal bile duct malignancy. CCA is intrinsically resistant to standard chemotherapy, responds poorly to it, and has a poor prognosis. Effective treatments for cholangiocarcinoma remain elusive, and a breakthrough in CCA treatment is still awaited.
