Hypersensitization to a food allergen can occur in the absence of immediate allergic reactions, a condition referred to as asymptomatic sensitization. Using mice asymptomatically sensitized to a bovine whey allergen, β-lactoglobulin (BLG, Bos d 5), we have previously shown that chronic exposure to the allergen results in behavior changes with increased neuroinflammation and cortical demyelination. However, whether allergen avoidance can resolve these pathologies is unknown. Thus, we aimed to compare immunological and behavioral changes in sham- or BLG-sensitized mice with or without the removal of dietary whey after the mice had consumed either a control diet (CTL) or a whey-protein-containing …

Alzheimer’s disease (AD) is the most common neurodegenerative disease, with β-amyloid(Aβ) plaque deposition being one of the hallmark pathologies. However, the etiology of AD remains elusive. While chronic inflammation from recurrent infections or injury seems to contribute to AD development, it is unclear whether atopic diseases, such as allergies, are associated with AD. We previously reported that continuous consumption of a whey protein(WP) -containing diet led to lasting neuro inflammation in C57BL/6J mice that were sensitized but tolerant to a bovine milk allergen, β-lactoglobulin (BLG;Bosd5). Thus, we hypothesized that the persisting neuroinflammation due to repeated allergen consumption would exacerbate AD …

Cow’s milk allergy (CMA) often manifests as milder reactions and may be linked to neurological problems. Previously, we demonstrated that C57BL/6J mice sensitized to a bovine whey allergen, β-lactoglobulin (BLG, Bos d 5), moderately increased BLG-specific IgE levels and exhibited behavioral changes without severe allergic reactions. When these non-anaphylactic CMA mice were placed on a whey-protein (WP)-containing diet for 2 weeks to simulate continuous dairy consumption, we found neuropathology indicative of neuroinflammation and cortical demyelination. Since immune cells migrate to the central nervous system (CNS) and promote neuroinflammation in demyelinating conditions such as multiple sclerosis, we hypothesized that the number …

Using a mouse model of cow’s milk allergy (CMA), we previously showed that C57BL/6J mice sensitized to a bovine whey allergen, β-lactoglobulin (BLG), exhibited anxiety/depression-like behavior and neuroinflammation in the absence of overt anaphylaxis upon allergen exposure

▪ Food allergy is often comorbid with neuropsychiatric disorders such as anxiety1,2, depression1,2, OCD3, ADD/ADHD4, and autism5. ➢ The mechanism of how food allergy may impact brain function and behavior in certain allergic individuals has yet to be elucidated.
▪ Mast cells (MCs) are not only the effector cell of the hypersensitivity response but are also important in maintaining brain homeostasis6. ➢ MCs have been implicated in neuropsychiatric and neurodegenerative disorders such as multiple sclerosis7,8.
▪ We have previously found in a mouse model of cow’s milk allergy (CMA) that intracranial MC numbers9 and histamine 3 receptor (H3R)10 increased after …
