Scientists transform skin bacterium into a topical vaccine that you rub onto your skin, a needle-free approach that would eliminate reactions like fever, swelling and pain. Topical application generated enough antibodies to successfully protect mice from 6 times the lethal dose of tetanus toxin.

🧠 Scientists have uncovered how skin cells "remember" past injuries and inflammation, a discovery made in mice and published on Thursday in Science. This "memory" is passed down through generations of skin cells via inherited patterns of gene expression and epigenetic marks on DNA.

🔬 This skin cell memory can be beneficial, allowing for faster healing of previous wounds. However, in conditions like psoriasis, this memory can lead to recurring flare-ups by making skin overly sensitive to triggers like stress.

🤖 Researchers utilized AI to identify specific genetic sequences in mice that contribute to this long-term skin stem cell memory, analyzing DNA behavior before and after injury.

💡 While this research was conducted on mice, the conserved biology suggests potential applicability to humans. Future human studies are anticipated, though they may be more complex due to differing cell regeneration and disease timescales.

Researchers from UQ’s Queensland Brain Institute have helped uncover a new clue about how the skin detects harmless warmth and cool. The team studied specialised nerve cells called thermoreceptors, and tracked how they responded to carefully controlled cooling and warming.
