An international consortium of thousands of scientists is creating the Human Cell Atlas, a three-dimensional map of all the cells in the body. The goal is to understand all the cells that make up human tissues, organs and systems, which will enable multiple medical applications. This collection of cell maps is openly available for navigation at single-cell resolution, identified through omics analyses that reveal the tridimensional distribution of each cell.

A year out from Leqembi’s approval for Alzheimer’s disease (AD), ongoing research coupled with artificial intelligence is advancing both radiopharmaceuticals and small-molecule drugs for AD diagnostics and treatment, speakers at the 2024 KoNECT-MOHW-MFDS conference said.

David Baker, Demis Hassabis and John Jumper share the 2024 Nobel Prize in Chemistry for their contributions to the science of protein structure. David Baker was awarded half the prize “for computational protein design,” according to the Royal Swedish Academy of Sciences. Hassabis and Jumper shared the other half “for protein structure prediction.”

Infection or cure? Scientists from Tel Aviv University and the University of Glasgow genetically modified the Toxoplasma gondii to bring a protein inside neurons. The novelty of using a protozoan that can travel from the gut to parasitize the CNS contrasts with the possibility of causing a disease. The scientists are already working on how to avoid it.

New single-step genome editing techniques that enable the insertion, inversion or deletion of long DNA sequences at specified genome positions have been demonstrated in bacteria.

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.

If we unraveled the DNA of the 46 chromosomes of a single human cell, it would barely measure 2 meters. If we did the same with the rest of the body, if we aligned the 3 billion base pairs of its 5 trillion cells, we could travel the distance from the Earth to the Sun more than 100 times. It seems unreachable. However, that is the unit of knowledge of the large sequencing projects achieved in 2023.

The field of peptides is exploding, Perpetual Medicines Corp. co-founder, chairman and CEO Kerry L. Blanchard recently told BioWorld, “with a projected growth rate far surpassing large and small molecules, and gene therapies. The area is underinvested, too, so this is a good opportunity to focus on peptide therapeutics.”
