messengers

specific cellular receptor molecules
  • first messengers extracellular biochemicals (e.g. lipoproteins, immunoglobulins, peptide hormones, neurotransmitters) that interact with cell membrane receptors to bring about cell membrane or intracellular effects

  • second messengers intracellular biochemicals (e.g. cyclic adenosine monophosphate [cAMP], inositol triphosphate [IP3], diacylglycerol [DAG]), calcium [Ca2+] formed when first messengers interact with intracellular enzymes; second messengers trigger the cell's response to the first messenger

As an example of the unique value proposition that Roaming Messenger brings, location based services can now be developed in conjunction with the Company's highly interactive and dynamic messengers.
Unlike current static technologies such as e-mail and text messaging, Roaming Messengers are dynamic, intelligent, real-time and location aware software "messengers" that can roam, locate and deliver highly interactive communications between responders in the field and back-end public safety applications.
These messengers are able to roam across wired and wireless devices, tracking people down on their multiple mobile or wired devices and interacting with them to get the right information to the right people at the right time.
