NORD has begun the review of all NORD GRANT UPDATES: submitted applications and will move forward with the selection process for the 2019 2018 NORD Grant: recipient. The previously announced 2018 NORD grant (see 2020 NORD Grant: Issues #63 and #64 of The ACDA is in the process of raising funds for ACDA Notes) in the amount a potential 2020 NORD grant. Please note the of $50,000 for ACDMPV minimum amount required for a NORD grant research was recently for ACDMPV research is $35,000. Please click awarded in June 2019 to Dr. HERE to donate. Csaba Galambos at University of Colorado Denver in Aurora, Colorado, USA for the study entitled, “The role of serotonin signaling in the pathogenesis of alveolar capillary dysplasia.” AT A GLANCE The ACDA initially presented Dr. Galambos’ Two possible therapeutic theory about the possible role of serotonin in approaches for ACDMPV ACDMPV patients in Issue #63 of ACDA (pending the development Notes, stating his prior study “contemplates a new area of exploration in both the of clinical trials): pathogenesis of and possible future Nanoparticle technology delivering a development of new therapeutic strategies for STAT3 protein to the lungs of ACDMPV ACDMPV. In the meantime, the next proposed babies, which could trigger the step of this research is to confirm whether or not ACDMPV patients display elevated development of blood vessels in the serotonin levels.” The ACDA will support Dr. lungs Galambos’ current research by facilitating the • Science Daily (June 19, 2019) collection of 24-hour urine samples of approved ACDMPV patients. • Medical Daily (June 20, 2019) Cell transplantation of c-KIT-positive Dr. Galambos is a pediatric pathologist and endothelial progenitor cells from donor prior NORD grant recipient for ACDMPV lungs, to increase the development of research in 2014. He has maintained a close pulmonary capillaries in ACDMPV working relationship with other key ACDMPV babies research institutions, including Baylor College of Medicine. Please read additional information (see pages 3- 4) about each of the above possible therapeutic approaches.
