Can Brazilian wasp venom cure cancer?
The venom of a wasp native to Brazil could be used in the fight against cancer, according to new University of Leeds research.Sep 2, 2015
What is wasp venom?
Bee and wasp venom contains a cocktail of substances, including mast-cell degranulation protein, hyaluronidase, acid phosphatase and lysophospholipase, histamine, dopamine, norepinephrine, and serotonin.
How big is a Brazilian wasp?
Description and identification. P. sericea individuals are medium-sized wasps, about 17 mm long. They are dark in color, and tend to be slow-flying and docile, unless they are disturbed.
Why does wasp sting hurt so much?
Wasp stings are packed full of venom, which is why they are so painful. Different people have different reactions and having one type of reaction doesn't mean you'll always have the same reaction every time you're stung. Though painful at first, you may not see much on the skin right away.
What does wasp venom do to your body?
Most deaths related to wasp stings are the result of immediate hypersensitivity reactions causing anaphylaxis. A single sting is sufficient to cause fatal anaphylaxis in hypersensitive patients. Massive envenomation can, likewise, cause death in non-allergic individuals, probably due to the toxic effects of the venom.
Are there Hornets in Brazil?

Are there Wasps in Brazil?
Social wasps are an outstanding component of the fauna in Brazilian biomes. Besides the complexity of their social behavior (Carpenter 1991) and of the architectonic diversity of their nests (Wenzel 1998), these insects are important predators of other insects in Neotropical ecosystems (Gobbi et al.
How can studying wasp venom provide information about possible leukemia treatments?
The venom of a wasp native to Brazil could be used as a weapon to fight cancer, scientists believe. A toxin in the sting kills cancer cells without harming normal cells, lab studies suggest. The University of Brazil team say the experimental therapy latches to tumour cells and makes them leak vital molecules.Sep 1, 2015
How does the Polybia paulista protect itself?
The social wasp Polybia paulista protects itself against predators by producing venom known to contain a powerful cancer-fighting ingredient. A new study reveals exactly how the venom's toxin -- called MP1 (Polybia-MP1) -- selectively kills cancer cells without harming normal cells. MP1 interacts with lipids that are abnormally distributed on the surface of cancer cells, creating gaping holes that allow molecules crucial for cell function to leak out.
What is MP1 in cancer?
MP1 interacts with lipids that are abnormally distributed on the surface of cancer cells, creating gaping holes that allow molecules crucial for cell function to leak out. Share: FULL STORY. The social wasp Polybia paulista protects itself against predators by producing venom known to contain a powerful cancer-fighting ingredient.
How does MP1 work?
MP1 acts against microbial pathogens by disrupting the bacterial cell membrane. Serendipitously, the antimicrobial peptide shows promise for protecting humans from cancer; it can inhibit the growth of prostate and bladder cancer cells, as well as multi-drug resistant leukemic cells.
Where are phospholipids located in the cell membrane?
In healthy cell membranes, phospholipids called phosphatidylserine (PS) and phosphatidylethanolamine (PE) are located in the inner membrane leaflet facing the inside of the cell. But in cancer cells, PS and PE are embedded in the outer membrane leaflet facing the cell surroundings. The researchers tested their theory by creating model membranes, ...
What is MP1 in cancer?
MP1 creates pores large enough for critical molecules to easily escape cancer cells. To test their hypothesis, the researchers created some model cell membranes. Some of these contained PS, some contained PE and some contained both. They then exposed their model membranes to MP1 and observed what happened.
Do wasps kill cancer?
Study reveals how wasp venom kills cancer cells. Wasps can be a menace, often found haunting picnics and fruit trees in the summer. However, the venom of one particular breed of wasp is known to contain a potent anticancer ingredient, and now researchers have shown precisely how the venom’s toxin selectively kills cancer cells.
What are the two lipids that make up the cell membrane?
One major difference is the positioning of two lipids that form part of the cell membrane: phosphatidylserine (PS) and phosphatidylethanolamine (PE). In cancer cells, PS and PE are located in the outer cell membrane facing outward from the cell, while in healthy cells, they are situated in the inner membrane and face inward.
What is bee venom used for?
Bee venom (BV) (api-toxin) has been widely used in the treatment of some immune-related diseases, as well as in recent times in treatment of tumors. Several cancer cells, including renal, lung, liver, prostate, bladder, and mammary cancer cells as well as leukemia cells, can be targets of bee venom peptides such as melittin and phospholipase A2.
Is bee venom a cancer treatment?
Bee venom in cancer therapy. Bee venom (BV) (api-toxin) has been widely used in the treatment of some immune-related diseases, as well as in recent times in treatment of tumors. Several cancer cells, including renal, lung, liver, prostate, bladder, and mammary cancer cells as well as leukemia cells, can be targets of bee venom …. ...
