      <Description>LA JOLLA INSTITUTE IS A NONPROFIT BIOMEDICAL RESEARCH INSTITUTE RANKED AMONG THE TOP FIVE ORGANIZATIONS IN THE WORLD FOR RESEARCH IMPACT IN IMMUNOLOGY. SPECIFICALLY, OUR SCIENTISTS CARRY OUT RESEARCH TO UNDERSTAND HOW THE IMMUNE SYSTEM WORKS, AND TO APPLY THAT KNOWLEDGE TO PREVENT OR CURE DISEASE. IMMUNE SYSTEM DISORDERS AFFECT MILLIONS AND INCLUDE MANY OF SOCIETY'S MOST DEBILITATING ILLNESSES. OUR RESEARCH FOCUSES ON FIVE MAJOR AREAS: 1. AUTOIMMUNE DISEASES SUCH AS TYPE 1 DIABETES AND RHEUMATOID ARTHRITIS 2. CANCER AND STIMULATING ANTI-TUMOR RESPONSES 3. INFECTIOUS DISEASES AND VACCINE DEVELOPMENT TO COMBAT TUBERCULOSIS, FLU, DENGUE VIRUS, AND OTHER DANGEROUS PATHOGENS 4. ALLERGY AND ASTHMA AND CONTROLLING HARMFUL IMMUNE REACTIONS 5. VASCULAR IMMUNOLOGY INCLUDING HEART DISEASE AND TYPE 2 DIABETES.MILLIONS OF PEOPLE AROUND THE WORLD DIE EACH YEAR FROM DISEASES THAT COULD BE CURED OR PREVENTED IF THE IMMUNE SYSTEM WERE FUNCTIONING PROPERLY. LA JOLLA INSTITUTE FOR ALLERGY AND IMMUNOLOGY IS RECOGNIZED AS A WORLD LEADER IN RESEARCH FOCUSED ON HARNESSING THE IMMUNE SYSTEM'S MECHANISMS TO PROMOTE HEALTH AND PREVENT DISEASE. LA JOLLA INSTITUTE SCIENTISTS BRING TO BEAR A COMPREHENSIVE RESEARCH EFFORT TO UNDERSTAND THE DIVERSE ASPECTS OF IMMUNE-MEDIATED DISEASES, WHICH INCLUDE MANY OF SOCIETY'S MOST DEBILITATING ILLNESSES. THESE RANGE FROM CHRONIC, SEVERE AUTOIMMUNE DISORDERS SUCH AS RHEUMATOID ARTHRITIS, TYPE 1 DIABETES, MULTIPLE SCLEROSIS, AND CROHN'S DISEASE TO IMMUNE SYSTEM MALFUNCTIONS UNDERLYING HEART DISEASE AND CANCER, THE NATION'S NO. 1 AND NO. 2 KILLERS RESPECTIVELY. ITS RESEARCHERS ALSO EXPLORE HOW THE IMMUNE SYSTEM RESPONDS TO INFECTIOUS DISEASES AND IS USING THIS KNOWLEDGE TO ADVANCE THE DEVELOPMENT OF VACCINES AGAINST DEADLY PATHOGENS SUCH AS MALARIA, TUBERCULOSIS, AND DENGUE FEVER, WHERE NO EFFECTIVE VACCINES CURRENTLY EXIST. A NONPROFIT, THE INSTITUTE WAS FOUNDED IN 1988 AND IS HOME TO 22 INDEPENDENT LABORATORIES, EACH OPERATED BY A LEADING SCIENTIST WHO OVERSEES EFFORTS TO UNLOCK THE MYSTERIES OF IMMUNE SYSTEM FUNCTIONING. SUPPORTING THESE EFFORTS ARE THE INSTITUTE'S MORE THAN 350 EMPLOYEES - ABOUT HALF OF WHOM HOLD DOCTORAL DEGREES (PH.D. OR M.D.) FROM NUMEROUS COUNTRIES AROUND THE WORLD. ALTHOUGH RELATIVELY YOUNG, THE INSTITUTE HAS ACCOMPLISHED MUCH IN ITS SHORT HISTORY, AND WAS RECENTLY RANKED AMONG THE TOP FIVE ORGANIZATIONS FOR RESEARCH IMPACT IN IMMUNOLOGY WORLDWIDE (AS MEASURED BY CITATIONS PER SCIENTIFIC PUBLICATION) BY THE RATING AGENCY THOMSON-REUTERS. IN ADDITION, THREE OF ITS SCIENTISTS ARE AMONG THE MOST HIGHLY CITED IMMUNOLOGISTS IN THE WORLD -- A DISTINCTION HELD BY LESS THAN ONE HALF OF ONE PERCENT OF ALL PUBLISHING SCIENTIFIC AUTHORS. SEVERAL OF ITS FACULTY MEMBERS ALSO SERVE ON NATIONAL INSTITUTES OF HEALTH (NIH) GRANT REVIEW PANELS, WHICH ARE APPOINTMENTS THAT SIGNAL A HIGH DEGREE OF RESPECT FROM PEERS. ITS SCIENTISTS ALSO REGULARLY PUBLISH RESEARCH PAPERS DESCRIBING THEIR LATEST FINDINGS, MANY OF THESE APPEARING IN THE WORLD'S MOST PRESTIGIOUS SCIENTIFIC JOURNALS.THE INSTITUTE RECEIVES THE MAJORITY OF ITS FUNDING THROUGH COMPETITIVE RESEARCH GRANTS FROM THE NIH AND IS GROWING ITS PHILANTHROPIC OPPORTUNITIES TO FULFILL PRIORITY NEEDS. THIS INCLUDES FUNDING FOR NEW AREAS OF RESEARCH, CUTTING-EDGE TECHNOLOGIES AND CONTINUING RECRUITMENT OF THE VERY BEST SCIENTISTS.IT IS GUIDED BY A BOARD OF DIRECTORS COMPOSED OF RESPECTED BUSINESS EXECUTIVES, SCIENTISTS AND OTHER COMMUNITY LEADERS WHO DONATE THEIR TIME TO OVERSEE THE INSTITUTE'S ACTIVITIES. A SCIENTIFIC ADVISORY BOARD OF DISTINGUISHED OUTSIDE SPECIALISTS CONDUCTS ANNUAL EVALUATIONS OF SCIENTIFIC PROGRESS AND REVIEWS FUTURE RESEARCH OBJECTIVES.LA JOLLA INSTITUTE RESEARCHERS CONTINUED TO MAKE IMPRESSIVE RESEARCH ADVANCEMENTS IN 2012, WITH 155 RESEARCH PAPERS PUBLISHED IN SCIENTIFIC JOURNALS, AN INCREASE OF MORE THAN 10 PERCENT OVER THE PREVIOUS YEAR. ALONG WITH INCREASING IN NUMBER, MANY OF THE INSTITUTE'S 2012 PAPERS (MORE THAN 20 PERCENT) WERE PUBLISHED IN HIGH-IMPACT, HIGH-PRESTIGE JOURNALS, A REFLECTION OF THE EXEMPLARY QUALITY OF THE INSTITUTE'S RESEARCH. THE INSTITUTE'S MAJOR PUBLISHED FINDINGS IN 2012 ILLUSTRATE THE RANGE AND POWER OF IMMUNOLOGY RESEARCH AND ITS IMPACT ON A BROAD GROUP OF HUMAN HEALTH ISSUES. THIS INCLUDED DR. KLAUS LEY'S DISCOVERY OF KEY INFLAMMATORY MECHANISMS THAT WORSEN ARTERIAL PLAQUE BUILDUP - A GROUNDBREAKING FINDING THAT LED TO HIS CURRENT EFFORTS TO DEVELOP A FIRST-EVER VACCINE FOR HEART DISEASE. SUCH A VACCINE WOULD WORK BY TEACHING THE BODY TO TOLERATE, RATHER THAN ATTACK, CERTAIN IMMUNE CELLS IN THE ARTERY WALL, THEREBY STOPPING THE INFLAMMATION THAT SIGNIFICANTLY FUELS PLAQUE BUILDUP. IF SUCCESSFUL, THE VACCINE WOULD PROVIDE DOCTORS A MAJOR NEW TOOL TO AID IN THE PREVENTION OF HEART DISEASE. AMONG THE INSTITUTE'S OTHER MAJOR FINDINGS IN 2012 WERE: DR. MITCHELL KRONENBERG'S DISCOVERY, PUBLISHED IN NATURE, OF A MOLECULE'S PREVIOUSLY UNKNOWN ROLE IN FIGHTING E. COLI AND OTHER BACTERIAL INFECTIONS, AN IMPORTANT REVELATION THAT COULD LEAD TO NEW TREATMENTS TO PROTECT PEOPLE FROM THESE DANGEROUS MICROORGANISMS; DR. BJOERN PETER'S IDENTIFICATION OF THE CELLULAR MECHANISM UNDERLYING POTENTIALLY FATAL DRUG REACTIONS IN MANY PEOPLE, A DISCOVERY THAT MAY ONE DAY ENABLE PRE-SCREENING TO PROTECT PEOPLE AT RISK OF THESE ALLERGIC DRUG REACTIONS, AND DR. MATTHIAS VON HERRATH'S FINDING OF THE SPECIFIC IMMUNE CELLS WHICH TRIGGER THE PANCREATIC BETA CELL DESTRUCTION UNDERLYING TYPE 1 DIABETES. THIS RESEARCH VERIFIES IN HUMANS INFORMATION PREVIOUSLY ONLY SHOWN IN MOUSE STUDIES AND PROVIDES A KEY CELLULAR TARGET FOR FIGHTING THIS DISEASE.IN ADDITION, FIVE INSTITUTE DISCOVERIES, UNDERLYING A NUMBER OF POTENTIAL THERAPIES, ADVANCED IN THE PHARMACEUTICAL PIPELINE IN 2012, THREE OF THEM IN CLINICAL TRIALS. THESE INCLUDE A TRIAL ON A NEW THERAPY FOR CROHN'S DISEASE AND ULCERATIVE COLITIS AND ANOTHER TRIAL, NOW ENTERING PHASE II, ON SICKLE CELL ANEMIA, A DEVASTATING ILLNESS THAT AFFECTS 100,000 AMERICANS AND SEVERAL MILLION PEOPLE WORLDWIDE. OTHER MAJOR HIGHLIGHTS IN 2012 INCLUDE: - RECOGNIZED AS A "BEST PLACE TO WORK" IN THE U.S. RESEARCH COMMUNITY -- THE INSTITUTE EARNED THE NATION'S NUMBER 7 SPOT FOR "BEST PLACES TO WORK FOR POSTDOCS." THE RANKING WAS BASED ON A U.S. SURVEY OF 2,081 POSTGRADUATE RESEARCHERS, KNOWN IN THE SCIENTIFIC COMMUNITY AS "POSTDOCS," CONDUCTED BY THE SCIENTIST MAGAZINE. POSTDOCS HAVE COMPLETED THEIR DOCTORAL DEGREES (PH.D., M.D., OR EQUIVALENT) AND TYPICALLY SPEND SEVERAL YEARS AT A RESEARCH INSTITUTION, GAINING TRAINING AND EXPERIENCE UNDER SENIOR SCIENTISTS. THE INSTITUTE ALSO RECEIVED HIGH MARKS AMONG ITS SENIOR SCIENTISTS, SCORING NUMBER 6 IN THE SCIENTIST'S "BEST PLACES TO WORK IN ACADEMIA" WORLDWIDE SURVEY IN 2012.- MAJOR AWARDS RECEIVED BY SEVERAL RESEARCHERS: DR. SHANE CROTTY WAS SELECTED FOR THE PRESTIGIOUS BIOSCIENCES INVESTIGATOR AWARD IN RECOGNITION OF HIS GROUNDBREAKING WORK IN VACCINE RESEARCH. THE AWARD IS PRESENTED ANNUALLY BY THE AMERICAN ASSOCIATION OF IMMUNOLOGISTS (AAI) AND RECOGNIZES EARLY-CAREER INVESTIGATORS FOR OUTSTANDING RESEARCH CONTRIBUTIONS TO THE FIELD OF IMMUNOLOGY; DR. RENATA M. PEREIRA, A RESEARCHER EXPLORING GENETIC CHANGES IN LEUKEMIA, WAS CHOSEN AS A PEW LATIN AMERICAN FELLOW IN THE BIOMEDICAL SCIENCES. DR. RENATA WAS ONE OF 10 EXCEPTIONAL YOUNG RESEARCHERS SELECTED NATIONWIDE FOR THE PRESTIGIOUS AWARD, WHICH PEW GIVES ANNUALLY TO ENABLE POSTDOCTORAL-LEVEL, LATIN AMERICAN SCIENTISTS TO WORK IN TOP LABORATORIES IN THE UNITED STATES. DR. PEREIRA CAME TO THE U.S. IN 2011 TO WORK IN THE LAB OF DR. ANJANA RAO, A PROMINENT GENETICS AND CELL BIOLOGY RESEARCHER AND A MEMBER OF THE NATIONAL ACADEMY OF SCIENCES; DR. KLAUS LEY WAS HONORED WITH A SPECIAL RECOGNITION AWARD IN VASCULAR BIOLOGY FROM THE AMERICAN HEART ASSOCIATION (AHA). THE AWARD WAS PRESENTED BY THE AHA'S COUNCIL ON ATHEROSCLEROSIS,THROMBOSIS AND VASCULAR BIOLOGY AND RECOGNIZES DR. LEY'S MANY CONTRIBUTIONS TO THE FIELD, WHICH FOCUSES ON HEART ATTACK, STROKE, AND PERIPHERAL ARTERIAL DISEASE. IN ADDITION TO THEIR RESEARCH ACTIVITIES IN 2012, INSTITUTE SCIENTISTS ALSO LECTURED AT MEDICAL RESEARCH SEMINARS THROUGHOUT THE WORLD AND ORGANIZED NUMEROUS SCIENTIFIC CONFERENCES. WHILE IT IS DIFFICULT TO DETERMINE THE NUMBER OF PERSONS BENEFITED BECAUSE OF THE BROAD APPLICABILITY OF LA JOLLA INSTITUTE'S FINDINGS AND ACCOMPLISHMENTS, THE INSTITUTE ESTIMATES THAT THOUSANDS OF RESEARCH AND CLINICAL SCIENTISTS ATTENDED THE ABOVE MENTIONED CONFERENCES, READ THE INSTITUTE'S PUBLICATIONS, AND/OR DIRECTLY COLLABORATED WITH OUR SCIENTISTS, AND AS A RESULT, NOW INCORPORATE PORTIONS OF OUR RESEARCH INTO THEIR WORK TO BETTER UNDERSTAND THE COMPLEXITY OF HUMAN BIOLOGY TO MORE EFFECTIVELY FIGHT DISEASE.</Description>
