VIDEO: Next-generation CAR T among highlights at Tandem Meetings

In this video, Maria Caterina Rotiroti, PhD, discusses notable presentations on chimeric antigen receptor T-cell therapy at Tandem Meetings | Transplantation & Cellular Therapy Meetings of ASTCT and CIBMTR.
“As a PhD working on CAR T-cell immunotherapy, I was particularly interested in the preclinical sessions focused on next-generation CAR designs,” Rotiroti, a postdoctoral fellow at Dana-Farber Cancer Institute, told Healio.
She also highlighted presentations investigating mechanisms of resistance following CAR T-cell therapy.

Early data show benefits of GLP-1s in breast cancer

The evolving story of GLP-1 receptor agonists in oncology has yet another new chapter.
Several studies presented at San Antonio Breast Cancer Symposium suggested the medications may help extend survival, reduce recurrence and mitigate chemotherapy-related toxicity. The benefits appeared consistent across a variety of disease subtypes.
However, investigators acknowledged the results must be interpreted with caution.
The findings came from retrospective cohort studies, so prospective validation will be essential. The possibility that GLP-1s may exacerbate endocrine therapy side effects, as well as

Gut microbe may be linked to lupus pathogenesis

A bacteria found in the gut may “very important” to the development of lupus and lupus nephritis, according to a speaker at the Basic and Clinical Immunology for the Busy Clinician symposium.
“We have evolved to interact with our microbes,” said Gregg Silverman, MD, of the New York University Grossman School of Medicine.
When those interactions go awry, the consequences can lead to more than just infection, he added.
“Maybe your immune system can wander,” Silverman said. “If there is an imbalance, bad things may happen.”

An experimental model reproduces creeping fat associated with Crohn’s disease and facilitates its study

A team of researchers from the Germans Trias i Pujol Research Institute (IGTP) and the Institut de Recerca Biomèdica Catalunya Sud (IRB CatSud, formerly IISPV) has published a study in the journal Inflammatory Bowel Diseases describing an experimental rat model that reproduces key features of creeping fat, the accumulation of adipose tissue surrounding inflamed intestinal segments and one of the characteristic pathological features of Crohn's disease.

Optical genome mapping detects additional genetic variants in nearly 20% of individuals with acute leukemia

New research assessing the efficacy of optical genome mapping (OGM) in a group of patients with acute leukemia has demonstrated that OGM provided reliable and robust analytical performance with high sensitivity and specificity in detecting genetic alterations. In nearly 20% of cases, additional genetic variants were found that standard tests had missed. Although these current standard assays retain value in the diagnostic workflow, the study, published in The Journal of Molecular Diagnostics, shows that OGM offers an exceptional complement and can replace certain elements of the current testing algorithm.

Inflammation-related protein changes could predict cognitive impairment after stroke

Researchers at The University of Manchester have found that tracking changes in a protein linked to inflammation (interleukin-6) after a stroke could help identify people at risk of later memory and thinking problems (also known as cognitive problems). The study also suggests that smoking may make people more at risk of memory and thinking problems in association with ongoing inflammation after a stroke.

Study uncovers a new mechanism explaining how chemicals affect sex hormones

Researchers at the University of Oulu have identified a previously unknown mechanism in humans that may explain why certain medicines and environmental chemicals disrupt the balance of sex hormones. The finding deepens scientific understanding of so-called endocrine disruptors—chemicals known to interfere with the body's hormonal systems. The study is published in the journal Basic & Clinical Pharmacology & Toxicology.
