Another Research Supports the Link Between Ticks Bite and Red Meat Allergy

Image byticksMost of the researchers and people believe that for a tick to trigger an unfavorably allergic immune reaction to alpha-gal in people, it is necessary for the tick to feed recently on the alpha-gal fresh blood of species. New research from the UNC School of Medicine exhibited at the American Academy of Allergy, Asthma, and Immunology (AAAAI) yearly meeting in San Francisco states otherwise.

Alpha-gal is a sugar found in most vertebrate blood, aside from people. At the point when people build up an unfavorably allergic immune response to it, this reaction can prompt a red meat hypersensitivity called alpha-gal disorder (AGS).

“Our original hypothesis was that humans developed the allergy after being exposed to alpha-gal through a tick that had fed on a deer, dog or other small mammals that has alpha-gal,” said Dr. Scott Commins, associate professor of medicine and pediatrics at UNC School of Medicine.

“This new data suggests that ticks can induce this immune response without requiring the mammal blood meal, which likely means the risk of each bite potentially leading to the allergy is higher than we anticipated.”

To achieve their goal, scientists stripped white blood cells of their Immunoglobulin E (IgE), antibodies developed by the immune system amid an unfavorably allergic immune response. The striped white blood cells were then covered with plasma from people with AGS and without AGS.

Furthermore, the researchers then added salivary extract of four types of ticks—Lone Star, Deer, Gulf Coast and American Dog to the cells. Some of the ticks fed on a blood carrying alpha-gal while some did not.

As per the expectations of researchers, saliva from the Lone Star and Deer ticks who fed on blood caused a reaction. However, one of the amazing things outcome was that the same type of ticks who did not feed on blood caused a similar reaction.

The saliva of Lone Star was found to be more harmful than others by 40%. On the other hand, saliva from both the Gulf Coast and the American Dog proved to be harmless and did not cause any response.

Since tests of both blood-fed and non-blood-fed tick saliva in these examinations showed a scope of reactivity, Commins says, “These results suggest that more tick bites than we initially suspected could pose a risk for developing red meat allergy.”

There is no treatment for AGS, other than staying away from nourishment and items that can cause a reaction. Commins urges everybody to avoid potential risk to prevent tick bites.
