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: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
