TNO Voeding (author), Pouvreau, L. (author), Gruppen, H. (author), van Koningsveld, G.A. (author), van den Broek, L.A.M. (author), Voragen, A.G.J. (author)The gene of the most abundant protease inhibitor in potato cv. Elkana was isolated and sequenced. The deduced amino acid sequence of this gene showed 98% identity with potato serine protease inhibitor (PSPI), a member of the Kunitz family. Therefore, the most abundant protease inhibitor was considered to be one of the isoforms of PSPI. The PSPI...article 2003

(author), TNO Preventie en Gezondheid (author)Monoclonal antibody (mAb) III-3b binds D-dimer with Kd = 1.4 × 10-10 M without cross-reaction with fibrin(ogen). The epitope for this mAb is in Bβ134-190, presumably in Bβ155-160. The latter site is buried in the coiled coil structure of fibrin(ogen) but it is exposed as a neoantigenic determinant in D-dimer upon plasmic lysis of fibrin. mAb III...article 2002

Seegers, J.F.M.L. (author)Evidence is accumulating that lactobacilli influence the immune response in a strain-dependent manner. This immunomodulatory capacity is important for the development of the immune response, and also identifies Lactobacillus as a potent oral vaccine carrier. Most of our current knowledge of the use of lactobacilli for vaccination purposes has...article 2002

One of the factors that may play a role in the immune- stimulating activity of particles is binding of allergen to particles. This may turn the particles into allergen carriers, resulting in antigen deposition within the altered...article 2001

Allergy is mediated by Th2 cells, which produce high levels of IL4 and IL5, and suppressive effects of lactic acid bacteria on the development of allergy have been attributed to their Th1...article 2001
