Imagine your brain as a beautiful garden, full of different plants and flowers. But as time goes by, some of these plants start to wilt and lose their vibrant colors. This is similar to what happens in our brains as we age. In a recent study, scientists wanted to understand how brain aging affects cattle, specifically focusing on the hippocampus – a region responsible for memories and learning. Using a powerful technique called liquid chromatography–tandem mass spectrometry (LC–MS/MS), they analyzed the proteins in the hippocampus of older grazing cows. The results revealed that 112 proteins were significantly altered in older cows compared to adult ones, with implications for myelination (a process involving nerve fiber insulation), synaptic vesicles (tiny structures involved in cell communication), metabolism, and calcium regulation. These findings provide valuable insights into the cognitive decline associated with aging and could potentially lead to the discovery of early markers of aging in cattle. Further research is needed to fully understand the role of the hippocampus in age-related cognitive decline and how this knowledge can improve animal welfare and farming practices.

Brain aging is a physiological process associated with physical and cognitive decline; however, in both humans and animals, it can be regarded as a risk factor for neurodegenerative disorders, such as Alzheimer’s disease. Among several brain regions, hippocampus appears to be more susceptible to detrimental effects of aging. Hippocampus belongs to limbic system and is mainly involved in declarative memories and context-dependent spatial-learning, whose integrity is compromised in an age-dependent manner. In the present work, taking advantage of liquid chromatography–tandem mass spectrometry (LC–MS/MS)-based proteomics, we sought to identify proteins differentially expressed in the hippocampus of the aged grazing milk cows. Our exploratory findings showed that, out of 707 identified proteins, 112 were significantly altered in old cattle, when compared to the adult controls, and functional clusterization highlighted their involvement in myelination, synaptic vesicle, metabolism, and calcium-related biological pathways. Overall, our preliminary data pave the way for the future studies, aimed at better characterizing the role of such a subcortical brain region in the age-dependent cognitive decline, as well as identifying early aging markers to improve animal welfare and husbandry practices of dairy cattle from intensive livestock.
