The binding of the sperm protein IZUMO1 to the oocyte receptor JUNO is an essential step in fertilization. Genetic deletion of IZUMO1 results in sterility, making this sperm protein a potential target for the development of an immunocontraceptive vaccine for the control of wildlife populations. However, contradictory results of the effect of immunization with IZUMO1 or IZUMO1-derived peptides have been reported. In this study, the effect of immunization with a recombinant mouse IZUMO1 peptide comprised of the extracellular Izumo, hairpin and Ig-like domains of IZUMO1 with different adjuvants was investigated in mice.

Nine Purdue University Department of Nutrition Science researchers and other colleagues collaborated on a report finding people respond very differently to the same foods, which is why “precision nutrition” — tailoring dietary advice to individuals — is gaining attention. In this review, the researchers studied how behaviors are shaped by a complex mix of biology and lived experience — including influences of age, sex, body size, genetics, culture, appetite, taste, smell, gut–brain signals and the microbiome.

Mycoponic biotechnology, inspired by hydroponics—a vital technology for agriculture research and space exploration, is limited by innate substrate contamination commonplace in commercial mycoproduction. Using micro-structured ceramic tubes as “substrate,” mycoponics provides mycelial cellular filaments with an air-phase/solid-state, antimicrobial interface for cellular liquid nutrient media uptake.

The Biomolecular Design Seed Grant awards research projects that accelerate collaborative research in the molecular biosciences at Purdue University. In the first year of this grant, two research projects have been selected. The projects are “AI-guided design of compact CRISPR-associated transposons for programmable gene insertion” submitted by Leifu Chang, Daisuke Kihara, and Ruqi Zhang and "A structured-conditioned, Small-Molecule-Driven Framework for Protein Design” submitted by Ramaswamy Subramanian and Ananth Grama.

Cell viability assays (CVAs) are widely used in cell biology, biomedical research, drug development, and biotechnology to assess cell health, proliferation, cytotoxicity, and functional activity under various conditions. Key applications span from everyday cell culture monitoring to drug screening and toxicology studies, immunology, vaccine development, and stem cell and regenerative medicine.

Accurate identification of phospholipid molecular species remains a major challenge in shotgun lipidomics because conventional tandem mass spectrometry typically resolves only one structural moiety at a time. This structural ambiguity limits confident lipid biomarker discovery and biological interpretation. Improving structural specificity without sacrificing analytical speed is therefore critical for lipidomics and disease-related studies.

Dehydration isn’t just a warm-weather problem. The risk remains in winter, possibly more so. "People tend to do a better job of staying hydrated in the summer because we’re sweating and hot," says Libby Richards, RN, interim head of the School of Nursing at Purdue University in West Lafayette, Ind. "But plenty of things happen in the winter that can lead to dehydration."

The body’s immune system is constantly on patrol, deploying billions of specialized cells to detect and destroy harmful invaders. Among the first to respond are neutrophils — fast-moving white blood cells that rush to sites of infection or injury. But how do these tiny first responders know where to go?

A new edition of a time-tested and influential veterinary work is on the market thanks to the scholarly efforts of two Purdue Veterinary Medicine faculty members and their team of U.S. and international experts from multiple veterinary schools. “Dellmann’s Textbook of Veterinary Histology” is an essential resource connecting the microscopic world of cells and tissues to the broader understanding of anatomy and physiology in domestic animals. Co-edited by Drs. Marxa Figueiredo and John Turek, associate professor and professor emeritus, respectively, in the college’s Department of Basic Medical Sciences (BMS), this latest edition integrates high-resolution electron and color micrographs with updated content that reflects current scientific and clinical knowledge.
