Red blood cells (RBCs) are biocompatible carriers that can be employed to deliver different bioactive substances. In the past few decades, many strategies have been developed to encapsulate or attach drugs to RBCs. Osmotic-based encapsulation methods have been industrialized recently, and some encapsulated RBC formulations have reached the clinical stage for treating tumors and neurological diseases. Inspired by the intrinsic properties of intact RBCs, some advanced delivery strategies have also been proposed. These delivery systems combine RBCs with other novel systems to further exploit and expand the application of RBCs. This review summarizes the clinical progress of drugs encapsulated into intact RBCs, focusing on the loading and clinical trials. It also introduces the latest advanced research based on developing prospects and limitations of intact RBCs drug delivery system (DDS), hoping to provide a reference for related research fields and further application potential of intact RBCs based drug delivery system.

Introduction: Accurate platelet (PLT) counting is crucial for disease diagnosis and treatment, especially under the condition of thrombocytopenia and platelet transfusion. A few PLT counting approaches have been established including impedance and fluorescent methods. The impedance PLT counting (PLT-I) approach could be interfered by small non-PLT particles in the blood, such as RBC/WBC fragments, microcytes, bacteria, and cryoglobulins.

Kingella kingae, an emerging pediatric pathogen, secretes the pore-forming toxin RtxA, which has been implicated in the development of various invasive infections. RtxA is synthesized as a protoxin (proRtxA), which gains its biological activity by fatty acylation of two lysine residues (K558 and K689) by the acyltransferase RtxC. The low acylation level of RtxA at K558 (2-23 %) suggests that the complete acylation at K689 is crucial for toxin activity.

Background: Malaria remains a critical disease. Leucinostatins from the fungus Purpureocillium lilacinum inhibited the transmission of Plasmodium falciparum to mosquitoes via contact.
Methods: Here, we modified the leucinostatin B (LB) C-terminus to make derivatives and examined their inhibition against malaria transmission to mosquitoes.

Red blood cells (RBCs) play a role in the regulation of vascular tone via release of adenosine triphosphate (ATP) into the vasculature in response to various stimuli. Interestingly, ApoE/LDLR double-deficient (ApoE/LDLR) mice, a murine model of atherosclerosis, display a higher exercise capacity compared to the age-matched controls. However, it is not known whether increased exercise capacity in ApoE/LDLR mice is linked to the altered ATP release from RBCs.

Metabolic dysfunction-associated steatohepatitis (MASH) is a major cause of a worldwide clinical and financial burden. Despite the tremendous efforts for untangling the molecular mechanisms, there is still a need for defining specific therapeutic targets. In this editorial, the author will focus on the role of erythrocyte death and hepatic erythrophagocytosis in MASH.
