Research group
Our research group focuses on elucidating the processes that drive the diversification of antigen recognition molecules in the immune system.
Decoding the Essential Foundations of Adaptive Immunity
Our research is centered on the evolutionary trajectory of immune system, orchestrating the interplay between innate and adaptive immunity—an exclusive feature in vertebrates. It is marked by the generation of diverse antigen receptors through somatic recombination/assembly of the host genome. This intricate process entails the delicate balance of minimizing the risk of genome disruption, potentially leading to cancer or cell death.
Our goal is to uncover the molecular mechanisms behind this diversification and to understand how host genome editing evolved within the immune system over time.
Approach
Our research focuses on exploring non-conventional model organisms from diverse evolutionary stages, which exhibit unique immune strategies potentially shaped by host genome editing processes. Central to our work is the study of a conserved enzyme family, fundamental across the tree of life, which plays a pivotal role in genome editing and evolutionary adaptation.
We employ a multidisciplinary approach, integrating in vitro biochemistry of these enzymes, single-cell omics, advanced imaging, computational genomics, and in vivo techniques. By combining molecular, cellular, and organismal studies, we aim to uncover robust insights into the mechanisms driving immune responses and genome dynamics.
Impact
Adaptive immunity provides crucial advantages in vertebrate systems, but it also poses challenges to genome integrity, potentially leading to carcinogenesis. Moreover, the immense diversity of antigen receptors generated by this process increases the risk of autoimmunity. Understanding how host genome editing is tightly regulated is therefore critical for preserving genome stability while still benefiting from adaptive immunity.
By uncovering the finely tuned mechanisms that regulate genome editing, we aim to develop new strategies to address immune dysfunction and modulate immune-related pathophysiology. Our research holds promise for creating interventions that could prevent or mitigate immune-driven diseases. Additionally, these enzymes have the potential to serve as new experimental tools for modifying genome information.
By leveraging non-conventional animal models, our work provides evolutionary insights with broad implications for understanding human immunity and advancing innovative therapeutic and biotechnological approaches.
