Novel immunotherapy approach to revert the main hallmarks of cat allergy

Researchers from the Department of Infection and Immunity of the Luxembourg Institute of Health (LIH) brought forward the potential of high doses of a specific adjuvant molecule, namely CpG oligonucleotide, in successfully modulating the immune system's allergic response to the main cat allergen Fel d 1, thereby inducing a tolerance-promoting reaction and reverting the main hallmarks of cat allergy.

$FDA approves cell-based gene therapy to treat adults with relapsed or refractory large-B-cell lymphoma$

FDA approves cell-based gene therapy to treat adults with relapsed or refractory large-B-cell lymphoma

Today, the U.S. Food and Drug Administration approved Breyanzi (lisocabtagene maraleucel), a cell-based gene therapy to treat adult patients with certain types of large B-cell lymphoma who have not responded to, or who have relapsed after, at least two other types of systemic treatment.

SARS-CoV-2 N501Y mutation adversely affects cellular immune response

Among these is the B.1.1.7 SARS-CoV-2 variant, with its characteristic N501Y mutation. A new preprint on the bioRxiv server reports the impact of this mutation on CD4 T cell responses, including antigen presentation on cells expressing Major Histocompatibility Complex (MHC) class II molecules.

Novel biomarker may help identify which pancreatic cancer patients respond to CD40 agonists

Inflammation in the blood could serve as a new biomarker to help identify patients with advanced pancreatic cancer who won't respond to the immune-stimulating drugs known as CD40 agonists, suggests a new study from researchers in the Abramson Cancer Center of the University of Pennsylvania published in JCI Insight.

POSTECH researchers discover mechanism behind intestinal epithelial lymphocyte differentiation

The intestine harbors the largest number of immune cells in our body. Since the intestine is constantly exposed to various antigens like bacteria and food, appropriate induction of gut immune cells plays a pivotal role in gut homeostasis.

Researchers develop thermostable RNA vaccine delivery platform

A new study describes the production of a new RNA vaccine delivery system that promises greater ease of storage and distribution. This could help boost vaccination rates in regions without adequate infrastructure for low-temperature storage.

South African SARS-CoV-2 variant neutralized by two Chinese vaccines in case study

A new study offers some reassuring findings, reporting the successful neutralization of the South African SARS-CoV-2 variant of concern (VOC) 501Y.V2 by two vaccines developed in China.

Viral load the main driver of SARS-CoV-2 transmission

A study conducted by researchers in the UK and Spain suggests that viral load is the main determinant of transmission risk in cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Could rapid result low sensitivity SARS-CoV-2 tests improve pandemic quarantine strategies?

Researchers in the USA have re-examined current testing and quarantining regimens for SARS-CoV-2. They suggest that the RT-PCR method and 14-day isolation rule may not be the most effective approach in managing viral transmission.

Long COVID-19 symptoms not associated with reduced cell-mediated immunity, finds study

A new preprint examines Long COVID-19, aiming to identify the underlying immunologic status in such patients.

One dose of VSV-vectored vaccine prevents SARS-CoV-2 replication in hamsters

A new preprint research paper posted to the bioRxiv server describes a viral vector vaccine candidate's efficacy to protect against SARS-CoV-2 replication in a hamster model.

J&J SARS-CoV-2 vaccine shows immunity in non-human primates 6 months after vaccination

A new preprint research paper released on the bioRxiv server discusses the findings from a model that assesses the association between the immunogenicity and protection conferred by a set of adenovirus- (Ad26)-vectored vaccines that express stabilized SARS-CoV-2 spike protein.

Rapid SARS-CoV-2 antigen test improved with silver amplification

A new preprint posted to the medRxiv server describes the use of silver amplification technology to develop a sensitive, rapid antigen test for COVID-19.

Single-dose vaccination effective for healthcare workers with prior SARS-CoV-2 infection

The findings reveal that healthcare workers previously infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) develop significantly higher antibody titers in response to a single dose of COVID-19 vaccine, as compared to healthcare workers without prior SARS-CoV-s infection. The study is currently available on the medRxiv* preprint server.

Immune dysregulation can affect the efficacy of CAR T therapy in some lymphoma patients

Chimeric antigen receptor T-cell therapy, or CAR T, has been a breakthrough in the treatment of blood cancers such as acute lymphoblastic leukemia and diffuse large B-cell lymphoma.

ZyCoV-D DNA vaccine immunogenic against SARS-CoV-2 in animal models

In the absence of effective therapeutics or preventives, vaccines have become the focus of attention. Though over 170 vaccines are in preclinical and about 60 in clinical development, very few are based on plasmid DNA technology. However, a new preprint research paper posted to the bioRxiv* server reports the immunogenicity of a DNA vaccine candidate.

Why SARS-CoV-2 B.1.1.7 is more virulent

A new preprint research paper by scientists from Sweden and India attempts to provide a preliminary answer to these questions using computational modeling. The research, which appears on the bioRxiv* server, predicts increased virulence with the new variant. If validated, this could help public health authorities prepare for new variants' possible impact as they emerge.
