Humanized NOG Mice for Intravaginal HIV Exposure and Treatment of HIV Infection
Published on: January 31, 2020
Summary
Traditional HIV vaccine development failed despite strong immune responses. A new strategy is needed, focusing on specific immune components that delay disease progression, rather than broad immunity.
Area of Science:
- Immunology
- Virology
- Vaccinology
Background:
- Despite robust humoral and cellular immunity against Human Immunodeficiency Virus (HIV), traditional vaccine development strategies have been unsuccessful.
- Neither specific antibodies nor CD8+ cytotoxic T-cells have provided primary protection in high-risk populations, questioning vaccine feasibility.
Discussion:
- The intact immune system's ineffectiveness, and potential role in enhancing HIV spread, necessitates a re-evaluation of immune responses.
- A specific subset of immune reactions plays a crucial role in delaying disease progression.
Key Insights:
- HIV vaccine development requires moving beyond traditional approaches that target broad immune responses.
- Focusing on specific immune mechanisms that control viral spread or delay pathogenesis is critical.
Outlook:
- Further dissection of immune reactions against HIV is indicated to inform novel vaccine design.
- A new HIV vaccine strategy may emerge from understanding protective immune subsets.

Vaccine Production
Vaccine production involves a sequence of upstream and downstream processes to generate a safe and effective immunological product. It begins with cultivating microorganisms, such as viruses or bacteria, to obtain antigenic material. For viral vaccines, mammalian host cells are grown in bioreactors and subsequently infected with the target virus. The virus replicates within the host cells, which are lysed to release viral particles. This lysate is then clarified through filtration or...
Genital Herpes
Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
Vaccines
Vaccines are among the most effective tools in preventive medicine, designed to prepare the immune system to recognize and combat infectious agents. By introducing antigens—substances that the immune system identifies as foreign—vaccines stimulate an adaptive immune response that leads to immunological memory. This immunological memory enables the body to mount a faster and more effective response upon future exposures to the actual pathogen.Vaccines can be categorized based on the type of...
Inhibitors of Virion Maturation and Assembly
As part of their replication cycle, certain viruses synthesize long precursor proteins called polyproteins within infected host cells. In human immunodeficiency virus (HIV), two major polyproteins are produced: Gag and Gag-Pol. The Gag polyprotein supplies the structural components of the virus, while Gag-Pol includes essential viral enzymes such as reverse transcriptase, integrase, and protease. After synthesis, these polyproteins move to the host cell membrane, where they assemble into an...

Overview
Immunodeficiency Diseases
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
