Market Impact

This breakthrough by India — Kanpur could significantly impact the pharmaceutical and biotechnology industries by enabling the design of more precise and effective drugs for immune-related diseases. The development of the R8Y molecule, which selectively targets C5aR2, opens new avenues for therapeutic development, potentially leading to new products and increased investment in this area.

Event Summary

Researchers at India — Kanpur, led by Professor Arun K. Shukla, have solved the long-standing mystery of the atypical immune receptor C5aR2. Using cryogenic-electron microscopy (cryo-EM), they discovered that C5aR2's intracellular structure differs significantly from its counterpart, C5aR1, explaining its non-canonical signalling. This understanding led to the development of R8Y, a molecule that selectively targets C5aR2, offering a precise tool to study complement activation. This advancement is expected to facilitate the design of novel drug molecules for immune-related diseases. The research was supported by various Indian government agencies and international collaborations, with plans to test R8Y in animal models for future therapeutic development.
