UNC 93 B1是Toll样受体(TLR)的关键调节因子,TLR是感知入侵病原体并管理先天免疫应答并将其从内质网递送到其各自的内体信号区室的模式识别受体。已知几种类型的TLR参与异基因造血干细胞移植(SCT)后的炎症过程,因此UNC 93 B1可能在其中发挥重要作用。我们研究了UNC 93 B1单核苷酸多态性(SNP)rs308328(T>C)对237例通过日本骨髓捐献者计划接受非亲缘HLA匹配骨髓移植(BMT)治疗恶性血液病患者的移植结局的影响。供体UNC 93 B1 C/C基因型与3年总生存率比供体UNC 93 B1 C/T或T/T基因型更好相关。因此,对UNC 93 B1 rs308328基因型的分析可能有助于选择供体,估计预后,并在同种异体SCT后制定治疗策略。
UNC-93 homolog B1 (UNC93B1) is a key regulator of toll-like receptors (TLRs), pattern recognition receptors that sense invading pathogens and manage the innate immune response and deliver them from the endoplasmic reticulum to their respective endosomal signaling compartments. Several types of TLRs are known to contribute to the inflammatory process after allogeneic hematopoietic stem cell transplantation (SCT), so UNC93B1 might play integral roles there. We investigated the influence of the UNC93B1 single-nucleotide polymorphism (SNP) rs308328 (T>C) on transplant outcomes in a cohort of 237 patients undergoing unrelated HLA-matched bone marrow transplantation (BMT) for hematologic malignancies through the Japan Marrow Donor Program. The donor UNC93B1 C/C genotype was associated with a better 3-year overall survival than the donor UNC93B1 C/T or T/T genotype. An analysis of the UNC93B1 rs308328 genotype may therefore be useful for selecting the donor, estimating the prognosis, and creating therapeutic strategies after allogeneic SCT.
