London, Jan 23 ( ANI ): Synthetic nanoparticles that target lymph nodes, where the most effective immune reactions
occur, could greatly boost vaccine responses, researchers say.
How that would affect the complex immune reaction
that causes type 1 diabetes, or whether breast-feeding might prevent it in some cases, remains unknown.
The wrong blood type can provoke serious immune reactions
that result in organ failure or death, so scientists have long sought a way to create an all-purpose red blood cell for transfusions that doesn't rely on costly blood typing or donations of a specific blood type.
Peptides are small, synthetically prepared substances with a low probability of causing an immune reaction
A We speculated that perhaps the combination of these two myelin components could be used in a vaccination-like approach to desensitize the animals, causing them to switch off their immune reaction
to these antigens and possibly prevent further disease damage.
The body often cranks out IgE as part of a misguided immune reaction
against noninfectious substances in the environment.
When filaria worms in mice sense that the mouse is mounting a strong immune reaction
, they change their life cycle, producing more offspring in the blood earlier.
Uppsala University researchers have observed that during mating, the females' genes are activated to roughly the same extent as when an immune reaction
Some patients have their spleens removed to relieve the aberrant immune reaction
The new study, published in the Journal of Allergy and Clinical Immunology, revealed surprising findings - the raised allergic antibodies that would support the immune reaction
theory were not present in two-thirds of the cases studied.
While conducting the study over beekeepers faced with daily stings in their work, the research team found that high doses of bee venom early in the year block an important immune reaction
for the remaining season, thus making them less likely to develop severe allergies.
Scientists haven't yet looked for any specific immune reaction
during pregnancy that targets later-born boys who become homosexual.
