Public Health Alerts provide concise, data-driven information on disease outbreaks and urgent health events. The new series, launched by NEJM Evidence and CIDRAP, offers expert-reviewed reports to support public health evidence-based care.
Researchers at ISTA have decoded the structure of HTLV-1 using Cryo-Electron Tomography, revealing a distinct viral lattice that differs from other retroviruses. This discovery could pave the way for novel treatment approaches to combat HTLV-1 infections, which affect 5-10 million people worldwide.
The researchers developed a novel viral reporter system called HIV-Tocky, which allows for real-time visualization of HIV dynamics post-viral infection. This innovation provides crucial insights into HIV-1 latency mechanisms and establishes a foundation for developing eradication strategies.
Researchers have discovered a rare case of retrovirus integration in a rodent from New Guinea, revealing a new model for virus colonization. The white-bellied mosaic-tailed rat's genome contains the 'complete Melomys woolly monkey virus', which has characteristics of both exogenous and endogenous viruses.
Researchers investigated the inactivation efficacy of different UV wavelengths against SARS-CoV-2 Omicron variants, finding similar inactivation properties across various wavelengths. The study highlights the potential of far-UVC light as a safe germicidal option for mitigating airborne virus transmission.
The study reveals diverse retroviruses in mouse lemurs, closely related to viruses in polar bears and domestic sheep, suggesting ancient infections. The discovery of endogenous retroviruses in these species provides new insights into the complex history of retroviral transmission among mammals.
Researchers found that ancient viral DNA in the human genome can act as antivirals, protecting human cells against certain viruses. The study, published in Science, provides proof of principle for this effect and reveals a potential genome defense system.
Researchers found that endogenous retrovirus RNA is present in all non-diseased tissue types, including cerebellum and thyroid tissues. This discovery has important clinical implications for the use of HML-2 expression as a cancer biomarker or therapeutic target.
The AAFP has released updated Feline Retrovirus Testing and Management Guidelines, providing current information on pathogenesis, diagnosis, prevention, and treatment. The guidelines aim to optimize care for feline patients infected with FeLV and FIV, and offer practical guidance for veterinarians and cat caregivers.
A unique immune system found in koalas protects their DNA from viruses, opening a new field of research. This 'immune response' helps prevent the spread of diseases like chlamydia and cancer.
Researchers discover that koala germ cells recognize and suppress retroviral invasion through a unique 'piRNA response' mechanism. This innate genome immune system can identify viral RNA and block its replication, providing a new understanding of how organisms defend against pathogen invasions.
A recent study published in PLOS Biology has uncovered a retrovirus not found in human genomes but present in African great apes and Old World monkeys. The authors estimate that gorillas and chimps were infected around 3-4 million years ago, while baboons and macaques were infected about 1.5 million years ago.
Researchers at the Fred Hutchinson Cancer Center discovered a secondary retroviral receptor, dubbed FELIX, crucial for feline leukemia virus (FeLV) infection. This discovery may provide a window into the pathway of retroviruses like HIV and potentially lead to therapies that disable the virus.
A multi-center study found that people infected with human T-lymphotropic virus type II (HTLV-II) are at a greater risk of acquiring bronchitis, bladder and kidney infections, oral herpes, and pneumonia. HTLV-II is primarily found in injection drug users and Amerindian tribes in South and Central America.
