Abstract
Insufficient accumulation of lipid nanoparticles (LNPs)-based mRNA vaccines in antigen presenting cells remains a key barrier to eliciting potent antitumor immune responses. Herein, we develop dendritic cells (DCs) targeting LNPs by taking advantage of mannose receptor-mediated endocytosis. Efficient delivery of mRNA to DCs is achieved in vitro and in vivo utilizing the sweet LNPs (STLNPs-Man). Intramuscular injection of mRNA vaccine (STLNPs-Man@mRNAOVA ) results in a four-fold higher uptake by DCs in comparison with commercially used LNPs. Benefiting from its DCs targeting ability, STLNPs-Man@mRNAOVA significantly promotes the antitumor performances, showing a comparable therapeutic efficacy by using one-fifth of the injection dosage as the vaccine prepared from normal LNPs, thus remarkably avoiding the side effects brought by conventional mRNA vaccines. More intriguingly, STLNPs-Man@mRNAOVA exhibits the ability to downregulate the expression of cytotoxic T-lymphocyte-associated protein 4 on T cells due to the blockade of CD206/CD45 axis, showing brilliant potentials in promoting antitumor efficacy combined with immune checkpoint blockade therapy.

Abstract
Chemoimmunotherapy can boost strong antitumor immune responses by triggering immunogenic cell death (ICD), which highlights a promising prospect in clinical applications. However, current chemoimmunotherapy shows limited efficacy due to the low delivery efficiency and insufficient immunogenicity of available chemotherapeutic drugs. A supramolecular polymeric nanomedicine (Pt-Tu@NP) is herein reported using cucurbit[7]uril-based host-guest recognition and noncovalent self-assembly. Pt-Tu@NPs have excellent biodistribution and strongly evoke the endoplasmic reticulum stress-mediated ICD of tumor cells, triggering potent antitumor immune responses by promoting dendritic cell (DC) maturation and cytotoxic T cell infiltration. The coordinated butyrate promotes a positive feedback regulation between DCs and CD8+ T cells. Pt-Tu@NPs stimulate immune cold tumors into hot ones, working in synergy with an immune checkpoint blockade to effectively suppress tumor growth and metastasis, which suggests a promising approach for cancer chemoimmunotherapy.

Abstract
Rapid identification of Candida species is significant for the diagnosis of vulvovaginal candidiasis (VVC). An integrated and multi-target system for the rapid, high-specificity, and high-sensitivity detection of four Candida species was developed. The system consists of a rapid sample processing cassette and a rapid nucleic acid analysis device. The cassette could process the Candida species to release nucleic acids in 15 min. The released nucleic acids were analyzed by the device as fast as within 30 min, using the loop-mediated isothermal amplification method. The four Candida species could be simultaneously identified, with each reaction using only 1.41 µL of reaction mixture, which was low cost. The RPT (rapid sample processing and testing) system could detect the four Candida species with high sensitivity (<2 CFU/reaction) and high specificity. The system also processed and analyzed 32 clinical samples, giving the results with high clinical sensitivity and specificity. Hence, the system was a significant and effective platform for the diagnosis of VVC. Furthermore, the period of validity of the reagents and chips used in the system was >90 days, and the system could also be used for the detection of bacteria.
