Black Widow is one of the most poisonous spiders whose venom is known to affect people’s nervous systems. For the first time, humans can heave a sigh of relief at the strides made in developing an antidote for the spider’s venom. Scientists at the Technical University of Braunschweig have developed and tested an antidote that can successfully neutralize any toxin from the black Widow spider known for its shiny black globe shape and belly.
The venom of the Black Widow spider, known to cause latrodectism, is a serious threat to human health. The initial symptoms of a black widow spider bite, including severe pain, burning sensation, and swelling, underscore the urgency of developing an effective antidote. The research at the Technical University of Braunschweig is a significant scientific breakthrough in this regard.
For a long time, horse serum has been used to counter the effects of black widow venom due to the animal’s potent antibodies. There has always been a need to develop an alternative antibody to counter the risks of using horse antibodies. Sometimes, people bitten by the spider don’t receive the horse serum because their proteins can cause unfavorable side effects like allergic reactions.
In developing the new, more effective black widow venom antidote, the researchers used an in vitro technical approach to display and test the efficacy against the venom. The approach relied on diverse gene collections from over 10 billion antibodies from which they fished out antibodies that bind the desired target, in this case, the toxin.
Antibodies created through this method can be produced with a uniform level of quality repeatedly since the human antibody’s DNA sequence is set. The research team successfully developed antibody candidates suitable for therapeutic antibody development. Of the antibodies produced, 45 of 75 demonstrated the ability to neutralize alpha-latrotoxin in a laboratory setting. Among these, the antibody MRU44-4-A1 was particularly notable for its exceptionally high neutralization capability.
While the study is yet to be tested in living organisms, the research team is taking every precaution to ensure the safety and efficacy of the antidote. Preclinical trials are currently underway, a crucial step in measuring the anti-venom’s efficacy before proceeding to human clinical trials. This meticulous approach instills confidence in the potential of the antidote.
