Infections during pregnancy can affect the placenta's ability to nourish and protect the fetus, potentially leading to complications like preeclampsia. Studying the placenta's response to infections could help anticipate problems for the baby and inform treatments for women's health.
A team of researchers from Penn State has developed a fluorescent molecular tag that tracks viral RNA and host interactions in real-time, allowing for the study of Zika and chikungunya viruses. The tool, called Mango-II, provides insight into the viral-host cell interaction, a key step to developing effective antiviral strategies.
A UCLA-led team will investigate how Zika virus damages the developing eye and explore potential treatments with a $2.7 million NIH grant. They will use lab-grown retinal pigment epithelium cells, mini retinas, and newborn mouse models to examine protein interactions and test promising compounds.
Researchers at La Jolla Institute for Immunology have developed a vaccine that uses T cells to fight Zika virus, but one vaccine, with both antibody and T cell protection, showed long-term protection against the virus. This discovery offers a new hope in the fight against Zika and its close viral relatives.
A nationally representative survey of empaneled adults found that most Americans understand how STIs spread, but there are significant gaps in public knowledge about which infections can be prevented through vaccination. The survey also revealed strong awareness of common transmission pathways and some basic facts about STIs.
Dr. James Earnest's research focuses on how the immune system responds to mosquito-borne viruses, aiming to create better preventative measures for dengue and Zika infections. He is collaborating with institutions in Mexico and Uganda to study immune responses over time, shedding light on effective memory B cells and antibodies.
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 developed a genetic method to produce dark males and pale females, making it easier to sort sex in mosquito control. The approach uses CRISPR gene editing to create an engineered sex-linked trait that enables fast and accurate sex separation without complex equipment.
Aedes aegypti and Aedes albopictus mosquitoes have been detected in the UK, posing a public health risk due to their role as vectors of diseases such as dengue and chikungunya. The detection highlights the importance of ongoing surveillance to reduce the risk of mosquito-borne diseases.
A new study predicts significant increase in mosquito-borne disease risk in Brazil by 2080, with higher temperatures and changing rainfall patterns contributing to the issue. Climate action could help mitigate this risk, reducing future disease outbreaks.
A new class of insecticide, called spatial emanators, provides protection for up to a year against mosquitoes that spread malaria, as well as dengue, West Nile, yellow fever, and Zika. The breakthrough offers lasting protection in areas where malaria is prevalent and can be used day and night without heating or electricity.
A study predicts that climate change will spread Dengue fever through Western Europe as the Asian tiger mosquito's habitat expands. Major cities like London and Paris are expected to become suitable for the mosquito, posing a significant threat to public health.
Europe is experiencing longer and more intense transmission seasons for mosquito-borne diseases, including West Nile virus infection and chikungunya virus disease. ECDC has warned that record-breaking outbreaks point to a 'new normal' in Europe, prompting the need for a robust response to protect public health.
A new study from the University of Alabama at Birmingham reveals that an antibody designed to fight dengue virus may also block Zika virus spread in reproductive organs. The therapy significantly reduces Zika replication in male and female reproductive tracts, providing a potential countermeasure against future outbreaks.
Dr. Xuyu Qian's pioneering research using MERFISH technology created an unprecedented developmental atlas of the human cerebral cortex, analyzing over 18 million single cells. His work aims to identify mechanisms disrupted in conditions like malformations and autism spectrum disorder.
The European Centre for Disease Prevention and Control (ECDC) has launched new weekly surveillance updates and public health guidance on mosquito-borne diseases, covering chikungunya, dengue, Zika, and West Nile viruses. The reports provide a comprehensive view of the evolving situation across European countries.
The Zika virus employs its host cells' autophagy mechanism to suppress proteins that would trigger an antiviral response, allowing for sustained infection. This unique strategy involves the manipulation of three proteins on the viral membrane, which are also involved in viral entry and replication.
Researchers from La Jolla Institute for Immunology and UC San Diego discover Zika virus blocks dendritic cells' ability to alert T cells, while dengue virus stimulates pro-inflammatory cytokines, leading to a stronger but uncontrolled immune response. Understanding these differences is key to developing life-saving vaccines.
Researchers developed a simple test that detects antibodies against four dengue virus serotypes and zika virus. The test achieved high sensitivity (87.8%) and specificity (91.4%), indicating its potential to monitor specific antibodies produced in response to exposure to the viruses.
Researchers discovered that Zika virus uses a tunneling strategy to spread in placental cells, hijacking mitochondria to augment its propagation and survival. The study found that the formation of tiny tunnels is driven exclusively by a Zika protein called NS1, which triggers tunnel formation in uninfected cells.
A new study reveals that Zika causes metabolic changes in human skin, making it a 'mosquito magnet' that attracts Aedes mosquitoes. The virus alters gene and protein expression in dermal fibroblasts, leading to increased production of volatile organic compounds that encourage mosquito bites.
The Zika virus hijacks the host protein ANKLE2 to assist its own reproduction, which is important for brain development. This interaction allows the virus to hide from the immune system and replicate more efficiently.
Researchers evaluated the efficacy and safety of using Zika virus for treating CNS tumors, finding that it reduces cell viability, inhibits growth, and decreases Bcl2 expression, potentially enhancing chemotherapy and radiotherapy effects. This ultimately led to significant tumor remission and improved long-term survival through an enh...
