M. Christine "Chris" Zink is the director of the Department of Molecular and Comparative Pathobiology at the Johns Hopkins School of Medicine. She also holds professorships in the Department of Pathology at Johns Hopkins and in the Department of Molecular Microbiology and Immunology at the Johns Hopkins Bloomberg School of Public Health. Zink researches the response of the immune system to retroviruses such as HIV and is currently investigating an animal model of antiretroviral therapy [1] and the potential of a common antibiotic to prevent HIV-associated neurocognitive disorders. [2] [3] [4]
As a veterinarian, Zink is known for consulting and writing on canine athletics [5] and is an expert on stem cell therapies for dogs. [6] She was named Outstanding Woman Veterinarian of the Year at the 2009 meeting of the American Veterinary Medical Association (AVMA). [7] Her books include Peak Performance: Coaching the Canine Athlete, Dog Health and Nutrition for Dummies, The Agility Advantage, and Jumping from A to Z: Teach Your Dog to Soar and Building the Canine Athlete: Strength, Stretching, Endurance and Body Awareness Exercises. [5] Zink is a Toronto-born Canadian [6] and has won several awards for her photography. [8]
Chris Zink earned a doctor of veterinary medicine (DVM) degree from the University of Guelph, where she also received a PhD in macrophage biology. [9] From 1985 to 1988, Zink completed a postdoctoral research fellowship with Opendra "Bill" Narayan at Johns Hopkins University, studying animal models of HIV pathogenesis. [9]
Following her postdoctoral work, Zink accepted an assistant professorship in the comparative medicine division at Johns Hopkins. She directed the division's postdoctoral training program from 1999. In 2000, Zink became a full professor. [9]
In 2007, Zink became the director of the Department of Molecular and Comparative Pathobiology at Johns Hopkins. [9] She follows long-time colleague Janice E. Clements, who had raised the comparative medicine division to department status. [10]
Zink's scientific research has focused on the effects of HIV and related lentiviruses on the central nervous system.
The Association for Women Veterinarians Foundation named Zink the Outstanding Woman Veterinarian of the Year in 2009. The honor was announced at the meeting of the American Veterinary Medical Association in Seattle in 2009.
Zidovudine (ZDV), also known as azidothymidine (AZT), was the first antiretroviral medication used to prevent and treat HIV/AIDS. It is generally recommended for use in combination with other antiretrovirals. It may be used to prevent mother-to-child spread during birth or after a needlestick injury or other potential exposure. It is sold both by itself and together as lamivudine/zidovudine and abacavir/lamivudine/zidovudine. It can be used by mouth or by slow injection into a vein.
The management of HIV/AIDS normally includes the use of multiple antiretroviral drugs as a strategy to control HIV infection. There are several classes of antiretroviral agents that act on different stages of the HIV life-cycle. The use of multiple drugs that act on different viral targets is known as highly active antiretroviral therapy (HAART). HAART decreases the patient's total burden of HIV, maintains function of the immune system, and prevents opportunistic infections that often lead to death. HAART also prevents the transmission of HIV between serodiscordant same-sex and opposite-sex partners so long as the HIV-positive partner maintains an undetectable viral load.
The spread of HIV/AIDS has affected millions of people worldwide; AIDS is considered a pandemic. The World Health Organization (WHO) estimated that in 2016 there were 36.7 million people worldwide living with HIV/AIDS, with 1.8 million new HIV infections per year and 1 million deaths due to AIDS. Misconceptions about HIV and AIDS arise from several different sources, from simple ignorance and misunderstandings about scientific knowledge regarding HIV infections and the cause of AIDS to misinformation propagated by individuals and groups with ideological stances that deny a causative relationship between HIV infection and the development of AIDS. Below is a list and explanations of some common misconceptions and their rebuttals.
Lamivudine/zidovudine, sold under the brand name Combivir among others, is a fixed-dose combination antiretroviral medication used to treat HIV/AIDS. It contains two antiretroviral medications, lamivudine and zidovudine. It is used together with other antiretrovirals. It is taken by mouth twice a day.

North Carolina State University College of Veterinary Medicine is an American educational institution located in Raleigh, North Carolina that offers master's and doctorate-level degree programs; interdisciplinary research in a range of veterinary and comparative medicine topics through centers, institutes, programs and laboratories; and external engagement through public service programs and activities.
Janice Ellen Clements is vice dean for faculty at the Johns Hopkins School of Medicine and the Mary Wallace Stanton Professor of Faculty Affairs. She is a professor in the departments of Molecular and Comparative Pathobiology, Neurology, and Pathology, and has a joint appointment in molecular biology and genetics. Her molecular biology and virology research examines lentiviruses and how they cause neurological diseases.
Opendra "Bill" Narayan was an HIV/AIDS researcher at the Johns Hopkins School of Medicine and the University of Kansas Medical Center. A veterinarian, Narayan researched animal models of HIV. His focus on finding a vaccine for retroviral infection had some success against a monkey retrovirus, SIV, and he is best known for engineering a type of HIV that could cause AIDS-like disease in monkeys.
Robert F. Siliciano is a professor of medicine at the Johns Hopkins University School of Medicine and an investigator with the Howard Hughes Medical Institute. Siliciano (sill-ih-CAH-noh) has a joint appointment in the Department of Molecular Biology and Genetics at Johns Hopkins. Siliciano researches the mechanisms by which the human immunodeficiency virus (HIV) remains latent in the human body.
Joel N. Blankson is a professor at the Johns Hopkins School of Medicine in the Department of Medicine, Division of Infectious Diseases. Blankson is an expert on HIV infection, particularly HIV latency and long-term control of HIV infection.

Elaine Ann Ostrander is an American geneticist at the National Human Genome Research Institute (NHGRI) of the National Institutes of Health (NIH) in Bethesda, Maryland. She holds a number of professional academic appointments, currently serving as Distinguished and Senior Investigator and head of the NHGRI Section of Comparative Genomics; and Chief of the Cancer Genetics and Comparative Genomics Branch. She is known for her research on prostate cancer susceptibility in humans and for conducting genetic investigations with the Canis familiaris —the domestic dog— model, which she has used to study disease susceptibility and frequency and other aspects of natural variation across mammals. In 2007, her laboratory showed that much of the variation in body size of domestic dogs is due to sequence changes in a single gene encoding a growth-promoting protein.
