Virology is the study of viruses and virus-like agents: their structure, classification and evolution, their ways to infect and exploit cells for virus reproduction, the diseases they cause, the techniques to isolate and culture them, and their use in research and therapy.
Scientists from the University of Colorado Anschutz Medical Campus recently identified how an RNA molecule from a virus develops a complex, three-dimensional structure, and is capable of changing its shape to hijack host proteins.
Torquetenovirus (TTV) is one of the viruses most frequently found in the human organism. It is also common in monkeys and domestic animals.
The human immunodeficiency virus (HIV-1) particularly attacks CD4 lymphocytes, a type of white blood cell considered to be the conductor of the immune system.
Researchers identified a greatly potent monoclonal antibody that aims at the spike protein of SARS-CoV-2.
A University of Alberta-led study shows that when it comes to susceptibility to infections and other health conditions, sex matters.
When people think of DNA, they visualize a string-like double helix structure. In reality, the DNA double helix in cells is supercoiled and constrained into loops. This supercoiling and looping are known to influence every aspect of DNA activity, but how this happens has not been clear.
The University of Kent's School of Biosciences and the Institute of Medical Virology at Goethe-University, Frankfurt am Main, have identified a protein that may critically contribute to severe forms of COVID-19.
A unique type of tiny antibody produced by llamas could provide a new frontline treatment against Covid-19 that can be taken by patients as a simple nasal spray.
HIV is a master of evading the immune system, using a variety of methods to prevent the body from being able to find and kill it.
Scientists at Weill Cornell Medicine have developed a computational technique that greatly increases the resolution of atomic force microscopy, a specialized type of microscope that "feels" the atoms at a surface.
COVID-19 continues to claim lives across the world and is infecting millions more. Although several vaccines have recently become available, making significant strides towards preventing COVID-19, what about the treatment of those who already have the infection?
Researchers from the Indian Institute of Technology Bombay shed light on the origins of Mimivirus and other giant viruses, helping us better understand a group of unique biological forms that shaped life on earth.
An innovative test that determines the quality and quantity of inactive HIV viruses in the genes of HIV patients may ultimately give scientists a better idea of effective drugs.
Cancer immunotherapy involves the activation of cells in the patient’s own immune system to fight tumor cells.
The body's immune response plays a crucial role in the course of a SARS-CoV-2 infection. In addition to antibodies, the so-called T-killer cells, are also responsible for detecting viruses in the body and eliminating them.
A new study indicates that protein kinases, which initiate the process that erodes the body’s immunity, significantly contribute to the immunodeficiency in HIV patients. Drugs that block these protein kinases may offer a solution to treating HIV patients whose immunity is not restored by antiretroviral therapy.
A paper published today in Nature shows how chemicals in the areas surrounding tumors--known as the tumor microenvironment--subvert the immune system and enable cancer to evade attack. These findings suggest that an existing drug could boost cancer immunotherapy.
Researchers at Baylor College of Medicine found that while most individuals responded to respiratory syncytial virus (RSV) natural reinfection with a typical sustained antibody response associated with protection, a few individuals surprisingly responded atypically, not being able to sustain the antibody response, which declined to levels that made the individuals susceptible to RSV reinfection.
Researchers are paving the way to a more in-depth understanding of the race between pathogens and the host organisms they search to infect.
According to a new study, non-steroidal anti-inflammatory drugs (NSAIDs) decreased both inflammatory and antibody responses to SARS-CoV-2 infection in mice.
