Social benefits of wound healing may not make any difference in animals with multiple partners

04.08.2004


A new study suggests that wounds on mice that prefer multiple mates heal at the same rate, whether the mice are housed with a mate or live in isolation.

But the same doesn’t ring true for monogamous mice, said Courtney DeVries, an assistant professor of psychology and neuroscience at Ohio State University.

She and Erica Glasper, a doctoral student in psychology at Ohio State, took a closer look at the effects social bonding had on wound healing in monogamous and non-monogamous deer mice. Non-monogamous males mate with more than one female during a breeding season. The researchers especially wanted to see if social interaction, or the lack of it, made a difference in the rate of wound healing in the non-monogamous mice.



It didn’t. In fact, levels of corticosterone – a stress hormone that rodents secrete – in the non-monogamous mice were the same whether they were paired or alone, and were also significantly lower than the corticosterone levels of paired, monogamous mice.

These findings are currently published in the online version of the journal Brain, Behavior and Immunity.

Social contact benefited the monogamous mice – corticosterone levels were lower, and wounds also healed faster. But separated pairs lost this benefit, even if the mice in a separated pair could still see each other through a screen.

Wounds on the non-monogamous mice – paired or unpaired – healed just as quickly as the wounds on the paired, monogamous mice.
"It suggests that the beneficial effects of social housing aren’t equivalent for all species, and may be limited to those that are monogamous or otherwise highly social," DeVries said. "Indeed, for some species, living with one or more companions may actually induce social stress and have deleterious effects on health.

"With humans, it can be difficult to alter someone’s social conditions, to get people to bond with others," she continued. "If we could identify a mechanism by which social interaction helps wounds heal, then we might be able to provide a pharmacological aid to facilitate healing in socially isolated people and other individuals at risk."

The research was supported by a seed grant from the Ohio State University Stress and Wound Healing Center.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
