“…This is in keeping with the observation that some of the shrimp allergens mentioned above, namely sarcoplasmic calcium-binding protein and myosin light chain, seem to play a more relevant role in the pediatric population [14,15], whereas all our patients were adults. However, in other adult populations the prevalence of sensitization to myosin light chain, arginine kinase or sarcoplasmic calcium-binding proteins largely exceeded that found in our patients [18]. It seems therefore possible to conclude that in Italian shrimp-allergic adults the relevance of the allergens mentioned above, namely AK, SCB and MLC, is limited, and most patients react against hitherto not described shrimp allergens showing higher molecular weights.…”

“…Este alérgeno tiene una identidad en la secuencia de aminoácidos del 86 % con la tropomiosina de otras especies de camarón y de insectos como la mosca Drosophila melanogaster (34). En la especie L. vannamei se ha caracterizado el Lit v 1 (34), al igual que el Pen i 1, presenta epítopos IgE lineales, distribuidos a lo largo de su secuencia, lo cual influye en su gran capacidad alergénica (34,35). Los epítopos con mayor frecuencia de reacción IgE son los contenidos entre los aminoácidos 1 a 63, con una frecuencia de 65 % a 60 % (35).…”

“…En un estudio en Estado Unidos se halló que la frecuencia de reacción IgE hacia la tropomiosina en niños alérgicos al camarón es de 94 %, mientras que en adultos alcanzó el 61 %. Esto sugiere que la sensibilización hacia este alérgeno disminuye con la edad; sin embargo, esto es un tema controversial (35). Entre las tropomiosinas de los crustáceos existe un alto grado de identidad en las secuencias de aminoácidos y las regiones de …”
