AB  - Natural antibodies (NAbs) are present in circulation even before the exposure to antigen and they exert various biological functions. They are polyreactive and mainly represented by immunoglobulin M (IgM), which is the first antibody produced in an ongoing immune response to infection and/or immunization. IgM is always secreted as a polymer with predominant pentameric structure, although other polymeric forms such as hexamer can be also formed. The biological functions of hexameric IgM are still not known and it is proposed that its existence as a NAb could be deleterious. However, the nature of IgM hexamers has not been investigated yet. In this paper, we have tested the expression of natural idiotope and antigenic specificities of pentameric and hexameric IgM polymers originating from sera of patients with Waldenstrom's macroglobulinemia, as well as patients suffering from recurrent urinary bacterial infections. We demonstrate that although pentameric IgM polymers can exist as natural and immune antibodies, IgM hexamers are exclusively immune and do not exist as NAbs.

AB  - Thaumatin-like proteins (TLPs) have been established as a new family of fruit and pollen allergens. The aim of this study was to develop a two-site ELISA for the quantification of the thaumatin-like kiwi allergen (Act d 2) in kiwifruit extracts and kiwifruit-containing food products. Genomic DNA (gDNA) of Act d 2 was amplified and the deduced amino acid sequence was determined to obtain a primary structure. Act d 2 purified from kiwifruit extract by HPLC was identified by Edman degradation and MS. Balb/c mice were immunized with Act d 2 for the production of mAbs by hybridoma technology. The optimized ELISA measured Act d 2 concentrations ranging from 0.2 to 9.0 ng/mL, with intra- and interassay coefficients of variation of 3.65 and 10.44%, respectively. The developed ELISA is a useful method for the quantification of the thaumatin-like kiwi allergen in kiwifruit extracts as well as the allergen level in kiwifruit-containing food products. It may be a helpful analytical tool for the evaluation of the stability (integrity) of fruit allergen extracts for in vitro diagnosis.
