Creating a Safe CAR T-Cell Therapy to Fight Solid Tumors in Children

Scientists at Children’s Hospital Los Angeles develop newer CAR T therapy that promises to be more effective and less toxic for children with neuroblastoma. Chimeric Antigen Receptor T-cell therapy—CAR T—has revolutionized leukemia treatment. Unfortunately, the therapy has not been effective for treating solid tumors including childhood cancers such as neuroblastoma. Preclinical studies using certain CAR

11,1 cases per million doses Allergic Reactions Including Anaphylaxis After Receipt of the First Dose of Pfizer-BioNTech COVID-19 Vaccine

Following implementation of vaccination, reports of anaphylaxis after the first dose of the Pfizer-BioNTech COVID-19 vaccine emerged.Anaphylaxis is a life-threatening allergic reaction that occurs rarelyafter vaccination, with onset typically within minutes to hours.Notifications and reports of suspected severe allergic reactions and anaphylaxis following vaccination were captured in the Vaccine Adverse Event Reporting System (VAERS), the

Emergence of a novel SARS-CoV-2 strain in Southern California, USA

Researchers in Cedars-Sinai Medical Center, Los Angeles found that the variant, originated in California, was present in more than half of samples tested last week by researchers in Los Angeles. In late December, scientists in California began searching coronavirus samples for a fast-spreading new variant that had just been identified in Britain. They found it, though in

Review of the epidemiology, susceptibility to infection, pathophysiology, immunology, complications, potential therapeutic options and response to vaccinations in people with diabetes, obesity and metabolic disorders showing mortality excess due to SARS-CoV-2 infection.

The increased prevalence of obesity, diabetes and cardiovascular risk factors in people hospitalized with severe COVID-19 illness has engendered considerable interest in the metabolic aspects of SARS-CoV-2-induced pathophysiology. In this paper published in Cell Metabolism are updated concepts informing how metabolic disorders and their comorbidities modify the susceptibility to, natural history and potential treatment of

A study shows early induction of functional SARS-CoV-2 specific T cells associates with rapid viral clearance and mild disease in COVID-19 patients

Virus-specific humoral and cellular immunity act synergistically to protect the host from viral infection. In this paper published on Cell Reports are interrogated the dynamic changes of virological and immunological parameters in 12 patients with symptomatic acute SARS-CoV-2 infection from disease onset to convalescence or death. SARS-CoV-2 viral RNA in the respiratory tract in parallel

New study shows that BioNTech-Pfizer SARS-CoV-2 vaccine protects against highly infectious UK variant

A new study found that antibodies in patients vaccinated against COVID-19 were able to neutralize a version of the new variant. Researchers tested 10 mutations of the B117 variant, which was first identified in the UK. The COVID-19 vaccine developed by BioNTech and Pfizer is likely to protect against the highly infectious variant of the virus, originally found

Hypothesis: Alpha-1-antitrypsin is a promising treatment option for COVID-19, due to its inhibition of neutrophil serine proteases “unfriendly fire”.

No definitive treatment for COVID-19 exists although promising results have been reported with remdesivir and glucocorticoids. Short of a truly effective preventive or curative vaccine against SARS-CoV-2, it is becoming increasingly clear that multiple pathophysiologic processes seen with COVID-19 as well as SARS-CoV-2 itself should be targeted. Because alpha-1-antitrypsin (AAT) embraces a panoply of biologic

SARS-CoV-2 501Y.V2 escapes neutralization by South African COVID-19 donor plasma

SARS-CoV-2 501Y.V2, a novel lineage of the coronavirus causing COVID-19, contains multiple mutations within two immunodominant domains of the spike protein. In a paper recently published on https://www.biorxiv.org/content/10.1101/2021.01.18.427166v1.full.pdf it’s shown that this lineage exhibits complete escape from three classes of therapeutically relevant monoclonal antibodies. Furthermore 501Y.V2 shows substantial or complete escape from neutralizing antibodies in
