Application


  • The activation mode of the mechanosensitive ion channel, MscL, by lysophosphatidylcholine differs from tension-induced gating: L-α-LPC is explored for its unique interaction with ion channels, suggesting its potential as a tool for studying channel mechanics and developing new therapeutic strategies for diseases linked to cellular mechanics (Mukherjee et al., 2014).

  • Aerosol delivery of an enhanced helper-dependent adenovirus formulation to rabbit lung using an intratracheal catheter: The use of L-α-LPC in enhancing the delivery of gene therapy vectors via aerosol demonstrates its utility in improving the efficiency of gene therapies, particularly for respiratory diseases (Koehler et al., 2005).

Trypanosomatid parasites are causative agents of neglected human diseases. Their lineage diverged early from the common eukaryotic ancestor, and they evolved singular mechanisms of gene expression that are crucial for their survival. Studies on unusual and essential molecular pathways lead
