Utilización de los recursos genéticos en un país que es centro de origen: el caso del cacao en el Perú

La producción peruana de cacao representa aproximadamente el 2% de la producción mundial; con una contribución muy reconocida por la calidad y diversidad de sus sabores y aromas. De milenario origen amazónico y probada utilización de hace por lo menos 5200 años, este cultivo recién ha sido visible para el desarrollo agrario en las dos últimas décadas, cuando se le ha utilizado con relativo éxito en la sustitución de cultivos ilegales de coca ¿Y qué tanto está contribuyendo la academia a la cadena de valor del cacao? Con carácter exploratorio, se registró y analizó una muestra de 44 tesis que tenían como objeto de estudio el cacao, obtenido por sus autores en los centros de producción y parcelas de productores. La mayor parte de estas tesis (41) estuvieron destinadas a obtener títulos profesionales, dos para optar el grado de magister y uno para obtener el grado de doctorado. Estas tesis se realizaron en universidades de 13 departamentos del Perú, contando Lima con el mayor número de tesis (12). Once tesis abarcaron actividades de investigación del germoplasma para la transformación y/o la innovación del cacao, confiriéndole así valor agregado con potencial uso comercial. Estas investigaciones estuvieron relacionadas con cuatro sectores productivos con un claro potencial comercial en el mercado global de recursos genéticos. En ningún caso, las investigaciones se realizaron bajo la seguridad jurídica del sistema de acceso a recursos genéticos y participación justa y equitativa de beneficios del Protocolo de Nagoya, del Convenio sobre la Diversidad Biológica.

The Peruvian production of cocoa represents, approximately, 2% of the world production, with a very recognized contribution because of the quality and diversity of its flavors and aromas. With a millenary Amazonian origin and proved utilization by at least 5200 years ago, this crop just became visible for the agrarian development in the last two decades, when it was used with relative success for the substitution of illegal coca crops. And how much is the academy contributing to the value chain of cocoa? A sample of 44 theses which cocoa obtained from production centers and farmers plots was their object of study, has been registered and analyzed in an exploratory way. 41 theses were to get professional titles, two for magister degree and one for doctorate degree. These theses were done in universities of 13 Department of Peru, where Lima reached the highest number (12). Eleven theses addressed germplasm research activities aimed to cocoa transformation and/or innovation, thus conferring added value with potential commercial use. These researches were related to four productive sectors with a clear potential in the global market of genetic resources. In any case, the studies were done under the legal certainty of the system of access to genetic resources and fair and equitable benefit-sharing of the Nagoya Protocol to the Convention on Biological Diversity.

Influence of Consumption of Two Peruvian Cocoa Populations on Mucosal and Systemic Immune Response in an Allergic Asthma Rat Model.

Different cocoa populations have demonstrated a protective role in a rat model of allergic asthma by attenuating the immunoglobulin (Ig) E synthesis and partially protecting against anaphylactic response. The aim of this study was to ascertain the effect of diets containing two native Peruvian cocoa populations ("Amazonas Peru" or APC, and "Criollo de Montaña" or CMC) and an ordinary cocoa (OC) on the bronchial compartment and the systemic and mucosal immune system in the same rat model of allergic asthma. Among other variables, cells and IgA content in the bronchoalveolar lavage fluid (BALF) and serum anti-allergen antibody response were analyzed. The three cocoa populations prevented the increase of the serum specific IgG1 (T helper 2 isotype). The three cocoa diets decreased asthma-induced granulocyte increase in the BALF, which was mainly due to the reduction in the proportion of eosinophils. Moreover, both the OC and CMC diets were able to prevent the leukocyte infiltration caused by asthma induction in both the trachea and nasal cavity and decreased the IgA in both fecal and BALF samples. Overall, these results highlight the potential of different cocoa populations in the prevention of allergic asthma.

Attenuating Effect of Peruvian Cocoa Populations on the Acute Asthmatic Response in Brown Norway Rats.

Cocoa contains bioactive components, which vary according to genetic and environmental factors. The present study aimed to ascertain the anti-allergic properties of native Peruvian cocoa populations ("Blanco de Piura" or BPC, "Amazonas Peru" or APC, "Criollo de Montaña" or CMC, "Chuncho" or CCC, and an ordinary cocoa or OC). To do so, after an initial in vitro approach, an in vivo study focused on the induction of an anaphylactic response associated with allergic asthma in Brown Norway rats was carried out. Based on their polyphenol content, antioxidant activity and in vitro effects, the APC and CMC were selected to be included in the in vivo study. Cocoa diets were tested in a model of allergic asthma in which anaphylactic response was assessed by changes in body temperature, motor activity and body weight. The concentration of specific immunoglobulin E (IgE), mast cell protease and leukotrienes was also quantified in serum and/or bronchoalveolar lavage fluid. CMC and OC populations exhibited a protective effect on the allergic asthma rat model as evidenced by means of a partial protection against anaphylactic response and, above all, in the synthesis of IgE and the release of mast cell protease.

Development and Characterization of an Allergic Asthma Rat Model for Interventional Studies.

Allergic asthma is one of the most common chronic diseases of the airways, however it still remains underdiagnosed and hence undertreated. Therefore, an allergic asthma rat model would be useful to be applied in future therapeutic strategy studies. The aim of the present study was to develop an objective model of allergic asthma in atopic rats that allows the induction and quantification of anaphylactic shock with quantitative variables. Female Brown Norway rats were intraperitoneally sensitized with ovalbumin (OVA), alum and Bordetella pertussis toxin and boosted a week later with OVA in alum. At day 28, all rats received an intranasal challenge with OVA. Anaphylactic response was accurately assessed by changes in motor activity and body temperature. Leukotriene concentration was determined in the bronchoalveolar lavage fluid (BALF), and total and IgE anti-OVA antibodies were quantified in blood and BALF samples. The asthmatic animals' motility and body temperature were reduced after the shock for at least 20 h. The asthmatic animals developed anti-OVA IgE antibodies both in BALF and in serum. These results show an effective and relatively rapid model of allergic asthma in female Brown Norway rats that allows the quantification of the anaphylactic response.
