Food allergies linked to childhood anxiety -- ScienceDaily

Among the children with a food allergy, 57 percent reported having symptoms of anxiety compared to 48 percent of children without a food allergy. Approximately 48 percent of the children had symptoms of depression with or without a food allergy. "Management of food allergy can be expensive both in terms of food shopping, meal preparation, and the cost of epinephrine auto-injectors, which expire annually," said Renee Goodwin, PhD, in the Department of Epidemiology at the Mailman School of Public Health and lead author. "These demands could result in higher levels of anxiety for those with fewer financial resources and further heighten anxiety symptoms in children and their caregivers." The results suggest that food allergy is particularly linked to elevated social anxiety and fear of social rejection and humiliation.

Scientists just got a step closer to creating a universal allergy treatment - ScienceAlert

They developed dissolvable nanoparticles out of an FDA-approved polymer, and then filled them with egg protein, before injecting them into mice that were allergic to eggs. Usually, these mice would develop an asthma-like response, but because the egg protein was safely stored inside the friend-looking nanoparticles, their bodies didn't react.  Even better, the nanoparticles were then cleaned up by macrophages, which are tasked with 'vacuuming up' any debris in the blood stream. And these macrophages are part of the innate immune system, which meant that the allergens were then processed as normal. "The vacuum-cleaner cell presents the allergen or antigen to the immune system in a way that says, 'No worries, this belongs here,'" said Miller. The immune system then shuts down its attack on that allergen, and gets reset to normal.

Immuno-psychiatry: When your body makes its own 'angel dust' -- ScienceDaily

"The atypical psychosis syndromes arising from the development of anti-NMDA receptor antibodies are extremely important to diagnosis and treat," commented Dr. John Krystal, Editor of Biological Psychiatry. "They may be easily misdiagnosed as the psychiatric disorders that they superficially resemble.. Nonetheless, these syndromes highlight the importance of NMDA receptor signaling for the genesis of symptoms associated with psychotic disorders."

Is depression a kind of allergic reaction?

Both cytokines and inflammation have been shown to rocket during depressive episodes, and – in people with bipolar – to drop off in periods of remission. Healthy people can also be temporarily put into a depressed, anxious state when given a vaccine that causes a spike in inflammation. Brain imaging studies of people injected with a typhoid vaccine found that this might be down to changes in the parts of the brain that process reward and punishment. There are other clues, too: people with inflammatory diseases such as rheumatoid arthritis tend to suffer more than average with depression; cancer patients given a drug called interferon alpha, which boosts their inflammatory response to help fight the cancer, often become depressed as a side-effect.

Protein from bacteria alleviates food allergy symptoms -- ScienceDaily

Lactobacillus might sound familiar when the topic of probiotics comes up, but they are only one of many types of bacteria that have proven health benefits. In a new study by the Academy for Immunology and Microbiology within the Institute for Basic Science (IBS) and the National Institute of Animal Science research project of Rural Development Administration, researchers have shown that the introduction of the probiotic Bifidobacterium longum KACC 91563 has the ability to reduce the effects of food allergies.

Round worms change immune system, reduce rejection of foreign bodies (like baby)

Infection with roundworm (Ascaris lumbricoides) is associated with earlier first births and shortened interbirth intervals, whereas infection with hookworm is associated with delayed first pregnancy and extended interbirth intervals. Thus, helminths may have important effects on human fertility that reflect physiological and immunological consequences of infection.
