The development of glucagon-like peptide 1 receptor (GLP-1R) agonists, such as semaglutide and tirzepatide, has been a game changer in the clinical management of overweight and obesity, but there is interpersonal variability in efficacy of these medications for weight loss, as well as in the incidence of undesired side effects. Investigators from the 23andMe Research Institute have shed some light on how variations in the GLP-1R and GIP receptor (GIPR) genes impact their effectiveness and the occurrence of side effects.
Drugs that mimic GLP-1 are widely used to treat diabetes and obesity, but it is not fully understood exactly how they produce many of their beneficial effects. Investigators from The Salk Institute for Biological Studies published a paper in Proceedings of the National Academy of Sciences shedding some light on the mechanisms. “Understanding this process more clearly could help researchers design the next generation of GLP-1-based treatments that are even more precise and effective,” first author Sam Van de Velde told BioWorld.
In an article published in Cell Host & Microbe on March 3, 2026, researchers at McMaster University in Canada and at the Hospital Universitario de La Princesa in Spain have shed some light on the impact of microbiota on peanut-driven allergy and anaphylaxis.

Researchers from the University of Sassari (Italy) and their collaborators have recently published findings from their research focused on the impact of one allelic variant in the CCND3 gene, encoding cyclin D3, on blood cell traits and resistance to malaria.
The neural and neuroimmune mechanisms behind myocardial infarction-triggered cardiac events, immune responses and activation of the nervous system remain largely unexplored. The heart and the brain talk to each other in what is known as cardioception. This communication between the two organs is orchestrated through neurons of the vagus nerve or the dorsal root ganglia, among others. Researchers from the University of California, San Diego have now shown that the dynamics of these interactions may play a crucial role in modulating inflammation, repair and cardiac functioning.
Bone metastasis represents a challenge in cancer therapy because of the independency of immunosuppression, neuropathic pain and osteolytic destruction. Recent evidence has suggested the tumor microenvironment can be reshaped through the activation of stimulator of interferon genes protein (STING) and pyroptosis induction.
The immune system is a critical factor of host survival, allowing resistance to infections and maintaining tissue integrity. The activation of immune responses requires precise regulation to assure a balance between the benefits and costs of these responses. Moreover, the theory of antagonistic pleiotropy proposes that traits beneficial to early-life fitness may sustain costs that manifest later in life, after the period of strongest natural selection, where aging introduces further complexities for cooperative defenses. As a result of this, hosts of different ages may manifest distinct disease courses despite infection with the same pathogen.
Researchers from the Medical School of Nanjing University hypothesized that in ulcerative colitis, the gut-resident macrophages may be compromised, leading to impaired integrity of the epithelial barrier. “From a basic science standpoint, our work uncovers a novel etiology of ulcerative colitis. From a translational perspective, it identifies a promising therapeutic target, potentially paving the way for developing effective drugs to treat or even cure the disease,” senior author Minsheng Zhu told BioWorld.
Researchers from the Baylor College of Medicine have characterized 100 conserved Alzheimer’s disease (AD) risk orthologue genes in Drosophila and found several with unknown roles in brain structure, function and stress resilience. The implication of this finding is that new pathways of neurodegeneration have been revealed, offering new insights into the genetic complexity of AD.
