NEC OncoImmunity发布用于发现新HLA等位基因和肿瘤特异性HLA变体的独特HLA分型技术

2022-02-18 国际文传 网络

该文献描述了一种进行新HLA等位基因分型和肿瘤HLA表征的新方法,用于指导个性化癌症免疫治疗。 

NEC OncoImmunity AS (NOI) 今天公布了一份文献。该文献描述了一种进行新HLA等位基因分型和肿瘤HLA表征的新方法,用于指导个性化癌症免疫治疗。 

该计算方法借用传统HLA分型技术的现有优势,从下一代测序数据中进行HLA分型,同时利用NOI的专有突变调用生物信息学来发现新的HLA等位基因和肿瘤特异性HLA变体。 

NOI与Ultimovacs ASA合作进行研究,利用深层靶向HLA测序技术和众多供体的血液来验证HLA分型方法。验证结果证实,在分辨率为2位数(1st field)和4位数(2nd field)的情况下,HLA分型成功率几乎达到100%。 

该方法发表在同行评审期刊《HLA》中。第一作者Anzar和她的同事还展示了该方法如何从个性化癌症疫苗设计时常规使用的标准测序数据中发现了一个获得正式命名的新型HLA等位基因。 

NEC OncoImmunity首席科学官Trevor Clancy博士表示:“这种方法是精准免疫治疗领域的一项重要进步。它将帮助HLA分型社区填补全球人类HLA库的空白,并帮助在疾病关联研究中识别新的HLA变体,同时提高HLA分型在器官移植和疫苗设计中的准确性。我们今后将利用我们生物信息学工具箱中的这一独特方法,进一步对HLA等位基因的变异与癌症免疫疗法反应之间的关系进行表征。”
