With a total of 7 patents, his work has advanced our understanding of T cell activation and regulation.

Latest Patents

One of his latest patents focuses on the modulation of T cell signaling threshold and T cell sensitivity to antigens. This research highlights the role of microRNAs (miRNAs), specifically miR-181a, in enhancing T cell activation. Increased expression of miR-181a in mature T cells leads to a marked increase in T cell sensitivity to peptide antigens. Furthermore, T cell blasts with higher miR-181a expression become reactive to antagonists. The study reveals that miR-181a dampens the expression of negative regulators in the T cell receptor (TCR) signaling pathway, resulting in a reduced TCR signaling threshold. This enhancement quantitatively and qualitatively improves T cell sensitivity to antigens.

Another significant patent involves precursor miRNA loop-modulated target regulation. This research demonstrates that modulation of mRNA activity can be achieved using precursor miRNAs (ta-RNAs). The study shows that pri- and pre-miRNAs can function independently of mature miRNAs. By modifying the stem and loop of ta-RNAs, the binding efficiency to target mRNA can be enhanced, leading to improved gene expression regulation.
