Study finds specific molecular barriers to SARS-CoV-2 replication in bat cells

Bat cells have specific molecular barriers to deal with SARS-CoV-2 replication, according to a study published in Journal of Virology —publication of the American Society of Microbiology— which includes the participation of Jordi Serra-Cobo, lecturer of the Faculty of Biology and the Biodiversity Research Institute (IRBio) of the University of Barcelona and expert on ecoepidemiological studies.

CDC: Novavax's COVID-19 vaccine can be used as another primary series option for adults

Today, CDC Director Rochelle P. Walensky, M.D., M.P.H., endorsed the CDC Advisory Committee on Immunization Practices' (ACIP) recommendation that Novavax's COVID-19 vaccine be used as another primary series option for adults ages 18 years and older.

SARS-CoV-2 hijacks tiny bridges that link infected cells with neurons to gain access to brain cells

COVID-19 often leads to neurological symptoms, such as a loss of taste or smell, or cognitive impairments (including memory loss and concentration difficulties), both during the acute phase of the disease and over the long term with "long COVID" syndrome.

Scientists explore SARS-CoV-2 spike protein and platelet-activating factor

Researchers assessed the association between platelet-activating factor (PAF) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike (S) protein.

Study provides the crucial antigenic map of SARS-CoV-2 variants of concern

Twenty different COVID-19 variants were effectively identified and neutralized after a third booster, according to the new study for which the University of Surrey provided the crucial antigenic map of variants of concern.

Study suggests a possible treatment approach for cancer and cardiovascular disease

A key molecule for cancer metastasis has been identified as a molecule already known for its involvement in cardiovascular disease, suggesting a possible treatment approach for both diseases simultaneously.

Study identifies risks in the use of CRISPR therapeutics

The researchers caution: "The CRISPR genome editing method is very effective, but not always safe. Sometimes cleaved chromosomes do not recover and genomic stability is compromised - which in the long run might promote cancer."

Study clarifies the role of intestinal white blood cells in colorectal cancer

Colorectal tumors are swarming with white blood cells, but whether these cells help or hinder the cancer is hotly debated.

Maternal antibodies may play a key role in protecting infants from congenital HCMV infections

Antibodies that summon virus-engulfing white blood cells may play an important role in protecting infants from potentially serious congenital infection with human cytomegalovirus (HCMV), according to a study led by an investigator at Weill Cornell Medicine and NewYork-Presbyterian.

Improving the immune defenses against blood cancer

For patients with lymphoma, multiple myeloma, or certain types of leukemia, treatment with chimeric antigen receptor T cells (CAR T cells) is sometimes the last chance of overcoming the cancer.

Antibodies' neutralization efficacy against Omicron variants BA.1 And BA.2 wanes rapidly, study finds

The Omicron variant of the SARS-CoV-2 virus was first detected in South Africa in November 2021. The high level of infectiousness of the virus and its ability to quickly spawn additional variants has also been observed in Germany: Since January 2022 the Omicron variant BA.1 has dominated here, followed in subsequent months by the variant BA.2.

LJI study about common cold coronaviruses may offer clues to how immunity can build up against SARS-CoV-2

For a glimpse into the future of SARS-CoV-2 immunity, scientists at La Jolla Institute for Immunology (LJI) are investigating how the immune system builds its defenses against common cold coronaviruses (CCCs).

A different approach to build a more durable, broadly effective COVID-19 vaccine

Researchers at University of California San Diego School of Medicine, with colleagues elsewhere, describe a different way to build a COVID-19 vaccine, one that would, in theory, remain effective against new and emerging variants and could be taken as a pill, by inhalation or other delivery methods.
