殺手細胞免疫球蛋白樣受體（killer cell immunoglobulin-like receptors or KIRs）：這些基因具有高度多態性，這意味著它們有許多變異，並影響 NK 細胞活性。研究發現特定的 KIR 變異是危險因子—KIR2DL5B(−)/KIR2DS3(+)/KIR2DS5(−)/KIR2DS4del(+)：
風險基因：KIR2DS3 和 KIR2DS4del
保護基因：KIR2DL5B 和 KIR2DS5
細胞特異性表達數量性狀位點（NK cell-specific expression quantitative trait loci or eQTLs）：這些是影響對 NK 細胞功能重要的基因表現水平的 DNA 區域。該研究確定了兩個 eQTL 為潛在風險因素：
Thank you very much for using our online reservation service. We are writing this in response to your inquiry regarding your ticket pickup.
We would like to inform you that your tickets need to be picked up at the station before boarding the train. As you may already know, your tickets cannot be collected at Kofu Station.
However, the tickets purchased from our website all can be collected on any day (including the train departure day), at any of our designated stations (including Haneda Airport Terminal 3). No application is required to change your pickup date or pickup location. However, we would recommend you to confirm the business hours of our designated station ticket counters beforehand at the following webpage. (Please click "Travelers without a rail pass".)
Also, the tickets purchased from our website can be picked up not only at the staffed office but also from the reserved-seat ticket vending machine. However, it is recommended that you come to the station during the hours the staffed ticket office is open in case you need assistance. We would ask you to arrive with plenty of time to issue your tickets, not immediately before your train departure.
We hope you have a safe and pleasant train journey.
