The GI tract mucosal surface provides a unique structural and immunological barrier
against various micro-organisms.
Since HIV also enters the body through mucosal surface of the vagina and rectum, an immunological barrier
at the port of entry could be the best chance to prevent infection.
In addition, nasally administered flu vaccine has the potential to create a local immunological barrier
and thus, better protection to influenza infection.
vice president of research and development at Nextran, who today is presenting at IBC's Xenotransplantation Conference in San Diego, stated "Through this collaboration with Cytel, we expect to minimize the most significant immunological barrier
to transplantation of pig organs -- hyperacute rejection.
The way these evade host defence system, cross cellular and immunological barriers
, manipulate host machinery for their propagation and thereby subvert the host functions to cause infections, is simply amazing.
Transplant physicians have been approached by individuals who wish to donate to a spouse or other family member, but are unable to do so because of blood type incompatibility or other immunological barriers
