Special Issue Information

Dear Colleagues,

Allergies are one of today's most common immune disorders; this is mostly because of an exaggerated immunoglobulin E-mediated immune response to harmless environmental allergens. The main translational goal to study allergies is to understand immune mechanisms, improve diagnosis, find a better and reliable immunotherapy, and manage the disease. Other factors, such as exposomes (parasites, ticks, drugs, heavy metals, plastic, and other contaminants) represent novel elements that act as important immunomodulatory agents in the allergic diseases and should be further investigated.

Therefore, the basis to achieve these goals are in the structural and immunological characterization of allergenic proteins; the interplay between allergens and innate and adaptive immunity; the development of novel therapeutic approaches; and the investigation of exposomes as immunomodulatory agents.

Potential topics include but are not limited to:

  • Allergens: new and old epitopes enrolled in IgE binding and allergenicity;
  • In silico discovery of allergens and prediction of allergenicity and allergic cross-reactivity;
  • Allergenicity prediction of novel foods;
  • Modulation of immune response by designed allergenic proteins;
  • Allergen structure interplay with the innate immunity;
  • Parasites and vectors as allergen transmitters;
  • Effects of environmental pollutants on allergenicity;
  • Effects of micro- and nano-plastics on protein allergenicity.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Tropomyosin is the major and predominant allergen among shellfish. This study developed an ultrasensitive immuno-PCR method for the quantification of crustacean tropomyosin in foods. The method couples sandwich ELISA with the real-time PCR (rtPCR) amplification of marker DNAs. Monoclonal anti-TPM antibody was the capture antibody, polyclonal rabbit anti-shrimp tropomyosin antibody was the detection antibody, while natural shrimp tropomyosin served as the standard. A double-stranded amino-DNA was covalently conjugated to a secondary anti-rabbit antibody and subsequently amplified and quantified via rtPCR. The quantification sensitivity of immuno-PCR was 20-fold higher than analogous ELISA, with LOQ 19.8 pg/mL. The developed immuno-PCR method is highly specific for the detection of crustacean tropomyosin and is highly precise in a broad concentration range. Tropomyosin recovery in the spiked vegetable soup was 87.7–115.6%. Crustacean tropomyosin was also quantified in commercial food products. The reported immuno-PCR assay is the most sensitive method for the quantification of crustacean tropomyosin and is the first immuno-PCR-based assay for the quantification of food allergen and food protein in general. The described method could be easily adapted for the specific and ultrasensitive immuno-PCR-based detection of traces of any food allergen that is currently being quantified with ELISA, which is of critical importance for people with food allergies.
