Background: In vitro (1R,3S)-1-methyl-1,2,3,4-tetrahydro-β-carboline-3-carboxyl-Lys(Pro-Ala-Lys)-Arg-Gly-Asp-Val (MTCA-KKV) adheres activated platelets, targets P-selectin and GPIIb/IIIa. This led to the development of MTCA-KKV as thrombus targeting nano-medicine.
Methods: MTCA-KKV was characterized by nano-feature, anti-thrombotic activity, thrombolytic activity, thrombus target and targeting release.
Results: In vivo 0.01 μmol/kg of MTCA-KKV formed nano-particles less than 100 nm in diameter, targeted thrombus, released anti-thrombotic and thrombolytic pharmacophores, prevented thrombosis and dissolved blood clots.
Conclusion: Based on the profiles of targeting thrombus, targeting release, inhibiting thrombosis and dissolving blood clots MTCA-KKV is a promising nano-medicine.

Background: Disseminated intravascular coagulation (DIC) is a severe complication in septic patients. The Japanese Ministry of Health and Welfare (JMHW)-DIC criteria, the first DIC criteria, were established in 1983, and several other criteria have been proposed since then, including the International Society on Thrombosis and Haemostasis (ISTH)-overt DIC criteria and the Japanese Association for Acute Medicine (JAAM) DIC criteria. This study aimed to look into the transition of DIC criteria used in randomized controlled trials (RCTs) for sepsis-induced DIC.

Platelets are nucleic-free cells with a lifespan of 7-10 days in the bloodstream, playing a crucial role in various physiological processes such as hemostasis, thrombus formation, tumor development and metastasis, inflammation, and host defense. By utilizing the unique structural and functional characteristics of platelets, platelet-modified nano-drugs can evade immune recognition and clearance and facilitate prolonged circulation , which ultimately allows the nanoparticles to reach sites of disease such as thrombi, tumors, inflammation, or bacterial infections, leading to specific adhesion and significantly enhancing the efficiency of targeted drug delivery. This paper reviews the novel design and application of platelet-derived biomaterials in various diseases in recent years and comprehensively demonstrates the potential of platelet-derived biomaterials in the fields of disease therapy and biodefence, which will provide a reference for advancing the development of platelet-derived biomaterials and clinical practice.

Despite the excellent advantages of biomicrorobots, such as autonomous navigation and targeting actuation, effective penetration and retention to deep lesion sites for effective therapy remains a longstanding challenge. Here, we present dual-engine cell microrobots, which we refer to as PR-robots, created by conjugating photosynthetic bacteria (PSB) with red blood cells (RBCs). The robots penetrate the tumor interior in swarms through combined hypoxic traction and ultrasound actuation (UA).

Protein disulfide isomerase (PDI) regulates multiple protein functions by catalyzing the oxidation, reduction, and isomerization of disulfide bonds. The enzyme is considered a potential target for treating thrombosis. We previously developed a potent PDI inhibitor, CPD, which contains the propiolamide as a warhead targeting cysteine residue in PDI.
