During the basic science morning track on the last day of this year’s Annual Congress of the European Hematology Association (EHA), the attention was focused on oncogenic transcription factors and complexes considered turning points within the acute myeloid leukemia (AML) arena.

Myeloproliferative neoplasms (MPNs) can only be cured, to date, using allogeneic stem cell transplantation which, in turn, only works for up to 20% of patients. As calreticulin (CALR) frameshift mutations are the second most common cause of MPNs, targeting this endoplasmic reticulum resident protein is one of the strategies emerging at the forefront of hematological malignancies research.

The success of a vaccine, a gene editing design for an untreated disease, or achieving cell engraftment after several attempts, comes from years of accumulated basic science studies, thousands of experiments, and clinical trials. Innumerable steps precede hits in gene and cell therapies before a first-time revelation, and most of them are failures at the time. At the 27th Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT) in Baltimore last week, several groups of scientists presented achievements that years ago looked impossible.

Immunotherapy-based cancer vaccines could permanently kill tumors by stimulating immune cells in multiple ways. At the 27th Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT), researchers presented their advances in this field with different techniques in the scientific symposium “Novel nucleic acid and cell-based vaccines for cancer,” organized by the infectious diseases and vaccines committee.

From glaucoma to Stargardt disease, age-related macular degeneration (AMD) to retinitis pigmentosa, or a corneal transplant to Bietti’s crystalline dystrophy, the 27th Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT) is working to bring some light to patients with age and congenital diseases that affect vision. From May 7-11, 2024, thousands of scientists are gathering in Baltimore to show their advances against the challenges of delivering genes and cells to the correct place, avoiding immunogenicity and improving diseases.

“Prenatal therapies are the next disruptive technologies in health care, which will advance and shape the future of patient care in the 21st century,” said Graça Almeida-Porada, a professor at the Fetal Research and Therapy Center of the Wake Forest Institute for Regenerative Medicine in Winston-Salem, North Carolina. At the American Society of Gene & Cell Therapy (ASGCT) annual meeting in Baltimore on May 5, 2024, Almeida-Porada introduced the first presentation of the scientific symposium “Prospects for Prenatal Gene and Cell Therapy.”

Japanese researchers have transplanted human induced pluripotent stem cells (iPSCs) in a primate model of myocardial infarction and were able to restore heart muscle and function in monkeys. Developed by Tokyo-based Heartseed Inc., the grafted iPSCs consist of clusters of purified heart muscle cells (cardiomyocyte spheroids) that are injected into the myocardial layer of the heart. Published in Circulation on April 26, 2024, the study showed that the cardiomyocyte spheroids survived long term and showed improved contractile function with low occurrence of post-transplant arrhythmias.

Females have a much greater risk of developing an autoimmune disease than males do. Eighty percent of autoimmune disease patients are female, and specific disorders can have an even more lopsided ratio – 90% of systemic lupus erythematosus (lupus) and almost 95% of Sjögren’s disease patients are female.

Cross-talk between macrophages and tumor cells could modulate cachexia in pancreatic cancer patients. A group of scientists from the University of Oklahoma has discovered a new pathway that promoted muscle wasting after the recruitment of this immune cell in the tumor microenvironment, activating cachexia-inducing factors. Macrophage depletion and the inhibition of this signaling could be developed as a therapeutic target for this condition.

Prior to this year’s Annual Meeting of the American Association for Cancer Research (AACR), it had been 14 years since metastasis had been the subject of a plenary session. So, the Tuesday session on “Evolution of the genome, microenvironment, and host through metastasis” had plenty of new insights to share.
