SPLUNC1-knockout mice was established in a LPS-induced acute lung injury (ALI) mouse model to study the anti-inflammatory effect of SPLUNC1. Results found that SPLUNC1 deficiency upregulated levels of ALI-related cytokines leading to more severe lung injury after LPS injection. Moreover, further data discovered that the presence of SPLUNC1 can suppress the recruitment of CD11b+Gr-1+ MDSCs to the spleen in LPS-induced ALI.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
