بياتريس هاهن (وُلدت في 13 فبراير 1955 في ميونخ بألمانيا) هي عالمة فيروسات أمريكية وباحثة في الهندسة الطبية. كما أن بياتريس أستاذة في الميكروبيولوجي في كلية بيرلمان للطب في جامعة بنسيلفانيا. في نوفمبر 2002، صنفت مجلة ديسكفر هان واحدة من أهم العالمات النساء في ذاك الوقت. اكتشفت هان أن فيروس نقص المناعة البشرية (HIV) نشأ في الرئيسيات الأخرى وانتقل إلى البشر. أثبتت هان ومجموعة أبحاثها أن قردة الشمبانزي الحية في جنوب الكاميرون كانت مستودعا طبيعيا لفيروسات نقص المناعة البشرية. طورت تقنيات غير جراحية لجمع البيانات الجينية من خلال إجراء مقارنات جينية بين فيروس نقص المناعة البشرية -1 ووجدوت أن الفيروسات قد اجتازت بين البشر وأنواع الرئيسيات غير البشرية من خلال اتصالات متعددة. نتج فيروس نقص المناعة البشرية عن العدوى بين الأنواع، حيث ينتقل فيروس الإيدز من الشمبانزي (SIVcpz) والغوريلا إلى البشر. قرر هان لاحقًا أن طفيل الملاريا قد انتقل أيضًا من القرود الأخرى إلى البشر، في حدث واحد. (ar) Beatrice H. Hahn (born February 13, 1955) is an American virologist and biomedical researcher best known for work which established that HIV, the virus causing AIDS, began as a virus passed from apes to humans. She is a professor of Medicine and Microbiology in the Perelman School of Medicine at the University of Pennsylvania. In November 2002, Discover magazine listed Hahn as one of the 50 most important women scientists. Hahn discovered that the human immunodeficiency virus (HIV) originated in other primates and spilled over to humans. Hahn and her research group established that wild-living chimpanzees in southern Cameroon were a natural reservoir of the closely related simian immunodeficiency viruses (SIVs). The team developed non-invasive techniques for gathering genetic data. By making comparisons between the genes of HIV-1 and SIVs, they found that SIVs had originated in apes, and had passed to humans through multiple connections. The simian versions of the virus (known as SIVcpz in chimpanzees, and SIVgor in gorillas) became the infection named HIV in humans. Hahn later determined that the malaria parasite also traversed from other primates to humans, in a single event. (en) |
