Ironically, the first person to be diagnosed with what is now Alzheimer’s disease was missing its major risk factor. When she first began showing symptoms of dementia in 1901, Auguste Deter was not particularly old. Despite Deter’s case, aging is the largest risk factor for developing Alzheimer’s, by a large margin. But “geroscience has not been translated into drugs for Alzheimer’s disease,” Howard Fillit, Alzheimer’s Drug Discovery Foundation co-founder and chief scientific officer, told BioWorld. “We’re just starting to see that cross-fertilization now.” This first article of a three-part BioWorld series on Alzheimer’s disease looks at how a group of researchers, as well as some startups, are trying to approach Alzheimer’s via an aging lens.

Scientists from the Australian National University have discovered the gene mutation responsible for causing psoriasis, and the findings could lead to improved diagnosis and treatment for patients with psoriasis and psoriatic arthritis, a chronic inflammatory skin disease. “We were able to identify the gene that could be important in enabling this progression from a skin-only condition to a skin-and-joint condition,” lead study author Chelisa Cardinez told BioWorld.

Deep learning algorithms have enabled the discovery of molecular structures of interest in biomedicine to design treatments against aggressive diseases such as idiopathic pulmonary fibrosis (IPF). Scientists at Insilico Medicine Inc. selected a target for IPF using artificial intelligence (AI), then designed an inhibitor to block it, and tested it in vitro, in vivo, and in clinical trials.

Eledon Pharmaceuticals Inc.’s tegoprubart, an investigational anti-CD40 ligand antibody, was used as part of the immunosuppressive regimen after the first-ever transplant of a kidney from a genetically modified pig to a human. The tegoprubart procedure was done March 16 at Massachusetts General Hospital on a 62-year-old man with end-stage renal disease.

After many years of testing different monoclonal antibodies against amyloid-β protein, the results obtained are far from being outstanding, and the control of the progression and symptoms of Alzheimer’s disease (AD) remains elusive. At the recent AD/PD 2024 conference held in Lisbon, new non-anti-amyloidogenic strategies in the starting line against AD were discussed. Professor Einar Sigurdsson from New York University gave a presentation entitled, “Single domain antibodies for therapy and diagnosis of synucleinopathies and tauopathies.”

Precision psychiatry got some love at two quite different meetings this week, the European Congress of Neuropsychopharmacology’s New Frontiers meeting and BioEurope Spring. The New Frontiers Meeting, an annual two-day meeting dedicated to cutting-edge issues in brain disease research, focused on big-picture and scientific – at times almost philosophical – questions of how to get to a classification scheme for brain disorders that aligns with the underlying biology.

One topic at the 31st Conference on Retroviruses and Opportunistic Infections (CROI 2024) held in Denver this month was that resistance to antiretroviral therapy (ART) has become a public health problem for people living with HIV. Without a vaccine or a cure, these patients depend on treatments that suppress viremia by preventing the virus from replicating. They are lifelong treatments and, until new advances succeed in eradicating the virus from reservoirs, the only option available.

The third day of the AD/PD 2024 conference in Lisbon started with a plenary lecture given by Professor Howard Fillit entitled, “Translating the biology of aging into new therapeutics for Alzheimer’s disease.” Fillit, a recognized neuroscientist and geriatrician, and co-founder of the Alzheimer’s Drug Discovery Foundation (ADDF), pointed to the geroscience hypothesis which postulates that targeting aging processes may result in preventive and therapeutic options for diseases of old age, including Alzheimer’s disease (AD).

Overall, the story of HIV is one of astounding success. But to declare victory, it will be necessary to develop a vaccine. The opening session of the 31st Conference on Retroviruses and Opportunistic Infections (CROI) 2024 looked back to the failures but also the advances in research, all the steps that over the years brought the basic science knowledge that could bring an HIV vaccine in the future. This year, the former director of the Viral Pathogenesis Laboratory at the NIAID Vaccine Research Center, Barney Graham, was named for the Bernard Field Lecture, where he presented “Modern vaccinology: a legacy of HIV research.”
