What does latrotoxin do to the body?

α-Latrotoxin is a presynaptic neurotoxin isolated from the venom of the black widow spider Latrodectus tredecimguttatus. It exerts toxic effects in the vertebrate central nervous system by depolarizing neurons, by increasing [Ca2+]i and by stimulating uncontrolled exocytosis of neurotransmitters from nerve terminals.

Where is latrotoxin found?

A latrotoxin is a high-molecular mass neurotoxin found in the venom of spiders of the genus Latrodectus (widow spiders) and also found in the venom of spider species, Steatoda nobilis. Latrotoxins are the main active components of the venom and are responsible for the symptoms of latrodectism.

How does latrotoxin affect acetylcholine?

Binding of α-latrotoxin to neuronal receptors results in massive release of acetylcholine (ACh) at the neuromuscular junction, resulting in profound muscle contraction. The symptoms of toxicosis relate to this neuromuscular activity and include muscle spasms, muscle pain, and abdominal rigidity.

How does α-latrotoxin may modulate exocytosis of ACh?

α-latrotoxin is a 130 kDa protein that binds to high-affinity receptors in nerve terminals, and causes massive stimulation of neurotransmitter release by exocytosis (Frontali et al., 1976; Tzeng et al., 1978).

What does black widow venom do to the body?

The black widow spider makes a venom that affects your nervous system. Some people are slightly affected by it, but others may have a severe response. Right away, you may feel severe pain, burning, swelling, and redness at the site.

How long do you have after a black widow bite?

Symptoms most often appear 30 minutes to 2 hours after the bite. They may last for 24 to 72 hours. Symptoms may be worse in children and older adults. The bite site will be cleaned.

What does a black widow bite do to you?

The black widow spider makes a venom that affects your nervous system. Some people are slightly affected by it, but others may have a severe response. Right away, you may feel severe pain, burning, swelling, and redness at the site. You may even see two fang marks.

What does black widow venom do to the nervous system?

Black widow venom hijacks the victim’s nervous system. Hour 1: The thighs, back, and shoulders are usually the first muscles to suffer stronger spasms. The venom causes the nervous system to dump all of its neurotransmitters.

What does acetylcholine do to the brain?

Brain and CNS Acetylcholine also acts at various sites within the CNS, where it can function as a neurotransmitter and as a neuromodulator. 1 It plays a role in motivation, arousal, attention, learning, and memory, and is also involved in promoting REM sleep.

What does black widow venom do to action potentials?

The venom of the black widow spider contains a toxin called α-latrotoxin. This is a large protein (120 kDa) that triggers synaptic vesicle exocytosis from presynaptic nerve terminals in the absence of action potential activity (Sudhof, 2001).

How does Black Widow Venom affect neurotransmitters?

The venom causes the nervous system to dump all of its neurotransmitters. Hours 1-3: Pain becomes more severe — causing the abdomen to have a board-like rigidity. Black widows have a cocktail of neurotoxins that enhance the effect of its main component alpha-latrotoxin.

What kind of treatment do you get for pancreatitis?

Treatment for acute or chronic pancreatitis may include a hospital stay to treat dehydration with intravenous (IV) fluids and, if you can swallow them, fluids by mouth pain medicine, and antibiotics by mouth or through an IV if you have an infection in your pancreas

How is the who ladder used to treat pancreatitis?

The WHO analgesia ladder was originally developed to treat pain due to cancer. However, over time, the indications have been extended, and the medical management of pain in acute pancreatitis can similarly be grounded on a modified version of the WHO ladder.

Are there consensus guidelines for chronic pancreatitis pain?

There is good news: consensus guidelines on chronic pancreatitis pain have been developed by an international team of experts. The task now is to make clinicians and patients aware of them. Abdominal pain is the most prevalent symptom of chronic pancreatitis, yet chronic pain is notoriously difficult to assess and treat.

How are pancreatic enzymes used to treat pancreatitis?

Enzymes to improve digestion. Pancreatic enzyme supplements can help your body break down and process the nutrients in the foods you eat. Pancreatic enzymes are taken with each meal. Changes to your diet. Your doctor may refer you to a dietitian who can help you plan low-fat meals that are high in nutrients.
