Interaction between tumour cells and macrophages enables cancer cells to evade immune detection and clearance by interfering with macrophage *** anti-phagocytic signals regulated by anti-phagocytic proteins are termed"don't eat me"signals;these signals include sialic acidbinding immunoglobulin-type lectin-10(Siglec-10)and the recently revealed CD24 immune checkpoint(ICP).In this study,we demonstrate that targeting a specific glycan on CD24 exhibits the potential to inhibit *** nigra agglutinin(SNA),a sialic acid-binding lectin,was employed to block CD24 and to enhance phagocytosis in melanoma *** addition,we prepared SNA-conjugated hollow gold-iron oxide nanoparticles for photothermal therapy of *** findings show that the combination treatment of SNA-conjugated photothermal nanoparticles and near-infrared exposure successfully augments tumour cell phagocytosis both in vitro and in vivo models.

A WDM(Wavelength Division Multiplexing) EPON(Ethernet Passive Optical Network) is an economical and efficient access network that has attracted significant research attention in recent years. A MAC(Media Access Control) Protocol of PON is based on TDMA(Time Division Multiple Access) basically, we can classify this protocol into a fixed length slot assignment method suitable for leased line supporting Qos(Quality of Service) and a variable length slot assignment method suitable for LAN/MAN with the best ...

Whole-genome shogun sequence(WGS)data generated by next-generation sequencing(NGS)platforms are a valuable resource for crop *** produced 5–6×WGS coverage of 44 Brassica oleracea breeding lines representing seven subspecies/morphotypes:cabbage,broccoli,cauliflower,kailan,kale,Brussels sprout,and kohlrabi to systematically evaluate the nuclear and chloroplast(Cp)diversity in the 44 *** breeding *** then exploited the impact of low-coverage NGS by evaluating nuclear genome diversity and assembly,annotation of complete chloroplast(Cp)genomes and 45 S nuclear ribosomal DNA(45S nrDNA)sequences,and copy number variation for major *** genome diversity analysis has revealed a total of 496463 SNPs and 37493 indels in the nuclear genome across the 44 ***,some SNPs showed subspecies enrichment at certain chromosomal *** assembly of complete Cp genomes contained 153361–153372 bp with 37 variants including SNPs and *** 45S nrDNA transcription unit was 5802 bp long with a total of 31 SNPs from the 44 *** phylogenetic tree inferred from the nuclear and Cp genomes coincided and clustered broccoli,cauliflower,and kailan in one group and cabbage,Brussels sprout,kale,and kohlrabi in another *** morphotypes diverged during the last 0.17 million *** Cp genome diversity reflected the unique cytoplasm of each subspecies,and revealed that the cytoplasm of many breeding lines was replaced and intermingled via inter-subspecies crosses during the breeding process *** polymorphic Cp markers provide a classification system for the cytoplasm types in ***,copy numbers of major transposable elements(TEs)showed high diversity among the 44 accessions,indicating that many TEs have become active ***,we demonstrated a comprehensive utilization of low-coverage NGS data and might shed light on the genetic diversity and evolution of diverse *** morphotypes.
