    摘要: The clustered regularly interspaced short palindromic repeat (CRISPR) gene editing technique, based on the non-homologous end-joining (NHEJ) repair pathway, can efficiently generate gene knockouts of variably sizes. More precise genome editing, either the insertion or deletion of a desired fragment, can be done by combining the homology-directed-repair (HDR) pathway with CRISPR cleavage. HDR-mediated gene knock-in experiments are inefficient, with no reports of successful gene knock-in with DNA fragments larger than 4 kb. Targeted insertion of large DNA fragments (7.4 and 5.8 kb) into the genomes of mouse embryonic stem cells and zygotes, respectively, using the CRISPR/HDR technique without NHEJ inhibitors was performed and indicate that CRISPR/HDR without NHEJ inhibitors can result in highly efficient gene knock-in, equivalent to CRISPR/HDR with NHEJ inhibitors. Although NHEJ is the dominant repair pathway associated with CRISPR-mediated double-strand breaks (DSBs), and biallelic gene knock-ins are common, NHEJ and biallelic gene knock-ins were not detected.

    摘要: Anti-cytokine therapy has revolutionized immunological disease treatment, but is not always effective and subject to treatment resistance as the cytokine cascade is highly redundant and multiple cytokines are involved in inflammation. Targeting a critical common regulator of inflammatory effectors is desirable. Lipopolysaccharide (LPS)-responsive beige-like anchor (LRBA) is a master regulator of multiple genes important for inflammation. Subcellular localization shows that LRBA translocated to the nucleus upon LPS stimulation and colocalized with multiple proteins associated with the endosome membrane system, indicating a critical role in membrane/vesicle trafficking essential for deposition, secretion and signal transduction of immune effectors. Deregulation, deficiency, down-regulation and overexpression of LRBA causes defective trafficking and signaling of immune effector molecules, resulting in immunodeficiency and autoimmunity diseases associated with a broader spectrum of severe symptoms when compared to other CVID genes. Modulating LRBA through antibodies, dominant negative mutants, or small interference RNA can be used to treat inflammatory diseases.
