Antioxidant Therapy Prevents Sexual Transmission of Zika in Mice

The antioxidant drug ebselen can forestall sexual transmission of Zika virus from male to feminine mice, in response to new analysis printed in PLOS Pathogens by Yogy Simanjuntak and colleagues at Academia Sinica, Taipei, Taiwan. The outcomes trace at a possible position for ebselen in stopping Zika unfold amongst people.

Zika virus often causes delicate signs in people however has been linked with congenital microcephaly and Guillain-Barré syndrome. The virus jumps from individual to individual primarily by way of mosquitos carrying the illness, however latest analysis means that sexual transmission can be potential — most frequently from males to ladies.

Within the absence of accepted medication or vaccines for Zika an infection, researchers are exploring alternatives to stop transmission. To realize new insights, Simanjuntak and colleagues investigated Zika an infection and transmission from male to feminine mice.

The analysis workforce first examined the consequences of Zika an infection on mouse testicular tissue. They discovered that the virus broken cells, impaired regular gene expression, broken sperm, and contaminated sperm cells themselves. Notably, Zika induced indicators of elevated testicular irritation and oxidative stress, a situation characterised by excessive ranges of doubtless damaging byproducts of regular mobile processes generally known as reactive oxygen species.

Subsequent, the researchers handled contaminated mice with ebselen, an anti-inflammatory and antioxidant drug that may neutralize reactive oxygen species. They discovered that ebselen each alleviated the noticed testicular signs and prevented sexual transmission of Zika by way of sperm from contaminated male mice to uninfected feminine mice.

Whereas additional analysis is required to guage the efficacy of ebselen, these findings counsel a possible position for the drug in treating and stopping transmission of Zika in people. Ebselen is already being investigated in medical trials as a therapy for different ailments, together with acute ischemic stroke.
