不变自然杀伤T细胞(INKT)是一种天然淋巴细胞,对糖脂抗原具有独特的特异性,具有显著的免疫调节特性。共刺激相互作用在iNKT细胞反应中的作用最近受到了仔细的研究。尽管iNKT细胞及其原型糖脂激动剂α-Galacosylceramide(α-GalCer)在癌症或病毒性疾病患者中进行的几项临床试验中显示出了希望,但目前基于iNKT细胞的治疗远未奏效。T细胞受体(TCR)和共刺激分子在iNKT细胞上的同时靶向为优化这种治疗方法提供了一个令人兴奋的新机会。在这里,我们回顾了我们对iNKT细胞共刺激作用的理解的最新进展,并根据iNKT细胞对疾病定制的糖脂的反应性和选择共刺激配体的基础上讨论了可能的治疗方式。
Invariant natural killer T (iNKT) cells are innate lymphocytes with unique specificity for glycolipid antigens and remarkable immunomodulatory properties. The role of costimulatory interactions in iNKT cell responses has recently come under scrutiny. Although iNKT cells and their prototype glycolipid agonist α-galactosylceramide (α-GalCer) have shown promise in several clinical trials conducted in patients with cancer or viral diseases, current iNKT cell-based therapies are far from effective. The concomitant targeting of T cell receptors (TCRs) and costimulatory molecules on iNKT cells represents an exciting new opportunity to optimize such therapeutic approaches. Here, we review recent advances in our understanding of iNKT cell costimulation and discuss potential treatment modalities based on the responsiveness of iNKT cells to disease-tailored glycolipids and select costimulatory ligands.
