"In essence, we propose a pre-clinical model of AIT for cat allergy, which mimics the conditions required for human AIT clinical trials and which is already optimized for future use in translational studies. Immunotherapy involves exposing people to larger and larger amounts of allergen in an attempt to change the immune system's response.. Meta-analyses have found that injections of allergens under the skin are … However, humans with mild cat allergies may undergo immunotherapy treatment. Immunotherapy is an ideal cat allergy treatment for the allergic owner who can't bear to part with her cats, no matter how much her pet's dander irritates her. The severity of symptoms can determine what course of treatment is available to the owner. Researchers from the Department of Infection and Immunity of the Luxembourg Institute of Health (LIH) have proposed a novel therapeutic approach to treat severe cat allergy. Insulinoma in Dogs and Cats. Inflammatory Bowel Disease in Dogs and Cats. Some allergy sufferers find relief in allergen immunotherapy, a periodic injection therapy designed to suppress the body's natural immune responses to the cat allergens. and Terms of Use. Immunotherapy is typically very effective in cats with allergies. Indeed, when looking at the Fel d 1-specific antibodies, the team noticed that AIT-treated allergic mice displayed lower levels of IgE, which are commonly associated with allergic responses, and higher levels of IgA and IgG, which can have anti-inflammatory properties.

In addition to reducing allergy symptoms, immunotherapy may help prevent new allergies. It might take a full year to recognize improvements. Cat allergy manifestations can range from mild symptoms to the development of severe conditions such as rhinitis and asthma, with potentially fatal outcomes. Researchers from the Department of Infection and Immunity of the Luxembourg Institute of Health (LIH) brought forward the potential of high doses of a specific adjuvant molecule, namely CpG oligonucleotide, in successfully modulating the immune system's allergic response to the main cat allergen Fel d 1, thereby inducing a tolerance-promoting reaction and reverting the main hallmarks of cat allergy. The researchers analysed the molecular mechanisms underlying this tolerance and proposed a pre-clinical allergen-specific immunotherapy approach to improve the treatment and control of this common type of allergy. While pharmacotherapy is an option for the milder forms, only allergen-specific immunotherapy (AIT) can ensure an effective and longer-lasting treatment in the more advanced cases. Infectious Anemia in Cats. Cat allergy manifestations can range from mild symptoms to the development of severe conditions such as rhinitis and asthma, with potentially fatal outcomes.

Various drug and nondrug therapies exist to alleviate … Based on our data, we believe that CpG deserves reconsideration as an effective AIT adjuvant in humans and that our work sets the bases for the development of novel successful immunotherapeutic treatments for allergies," concludes Prof Markus Ollert, Director of the LIH Department of Infection and Immunity and senior lead author of the study. The allergen element of cat dander is a protein from the cat's sebaceous glands. Quite strikingly, however, the researchers found that the mechanism underlying this allergy-protective action varies according to whether the treatment is administered as a vaccine to mice that had never previously been exposed to the Fel d 1 antigen, and which therefore did not present an existing allergic state, or under already established allergic conditions, as is the case in AIT. Cat allergen immunotherapy is a potential disease modifying treatment for patients with cat allergy.

Sufferers will experience sneezing, runny nose, sinus headache and teary eyes. Your feedback will go directly to Science X editors. Interestingly, AIT also triggered the appearance of a novel and unique type of Tregs, known as biTregs, which is even better equipped to counterbalance the allergic and inflammatory reaction in response to the antigen," adds Dr. Léonard.

More serious cases of allergies affect the lungs, causing wheezing or shortness of breath. Only an allergy test can tell for sure. Symptoms range from stuffy nose and itchy eyes, to hives, wheezing and asthma attacks. The researchers also noticed that, already very soon after AIT-injection, there was an increase in the tissues of AIT-treated mice in the abundance of immune cell types involved in allergy regulation and tolerance, namely plasmacytoid dendritic cells (pDCs), Natural Killer cells (NKs), regulatory T cells (T-regs) and regulatory B cells (B-regs).

While pharmacotherapy is an option for the milder forms, only allergen-specific immunotherapy (AIT) can ensure an effective and longer-lasting treatment in the more advanced cases. [9] [10] In its early stages, AIT utilized cat dander extract, which consists of microscopic dry skin flakes of cats, but later resorted to Fel d 1 due to issues of standardization. or, by Luxembourg Institute of Health. Nevertheless, there is still the need to improve cat AIT in terms of efficacy and safety. These allergen vaccines make up the build up portion of immunotherapy. Sufferers will experience sneezing, runny nose, sinus headache and teary eyes.

To study the cellular and clinical effects of an AIT based on the injection of the Fel d 1 allergen in combination with a high dose of CpG adjuvant, the team challenged Fel d 1-allergic mice with the allergen, both in the presence and absence of AIT. AIT typically consists in the subcutaneous injection of gradually increasing quantities of the allergen in question, until a critical dose is reached that induces long-term immune tolerance. In addition, AIT-treated allergic mice showed a reduction in the levels of certain pro-allergic cytokine molecules, produced by type 2 helper T cells (Th2), compared to untreated allergic animals. While pharmacotherapy is an option for the milder forms, only allergen-specific immunotherapy (AIT) can ensure an effective and longer-lasting treatment in the more advanced cases. Indeed, our study presents several novelties including the use of endotoxin-free Fel d 1 allergen, which is mandatory in the clinical setting, to prevent the onset of collateral inflammatory responses which could compromise the desired induction of the tolerance-promoting mechanisms. The information you enter will appear in your e-mail message and is not retained by Medical Xpress in any form. The elucidation of these alternative pathways opens up new insights for the future design of preventive and curative allergy vaccines using CpG adjuvant. This document is subject to copyright.

At this point, most of your feline allergy symptoms should have been alleviated. The full study results were published recently in the renowned international journal Allergy, the official journal of the European Academy of Allergy and Clinical Immunology (EAACI) and one of the top two journals worldwide in the allergy field. Researchers brought forward the potential of high doses of a specific adjuvant molecule, namely CpG oligonucleotide, in successfully modulating the immune system’s allergic response to the main cat allergen Fel d 1, thereby inducing a tolerance-promoting reaction and reverting the main hallmarks of cat allergy.

Keywords Felis domesticus allergen 1 , subcutaneous immunotherapy , sublingual immunotherapy , allergen-specific immunotherapy Cat allergen is particularly persistent and can remain in homes long after a cat is no longer there. The researchers hypothesized that the most effective cat AIT could be achieved by optimizing the response of immune system T- and B-cells through immune adjuvants to induce the production of antibodies against Fel d 1 while minimizing inflammatory reactions, thereby boosting immune tolerance to this allergen. While pharmacotherapy is an option for the milder forms, only allergen-specific immunotherapy (AIT) can ensure an effective and longer lasting treatment in the more advanced cases. Moreover, we show for the first time that the use of the maximum dose of CpG tolerated in humans has the ability to modulate the allergic response when combined with Fel d 1 allergen, with very favorable safety profiles and through a well-established and medically-approved delivery mode.
