Summary
Botulinum neurotoxins (BoNTs) are expanding into a superfamily. Structural studies reveal mechanisms for engineering these toxins for improved therapeutic applications.
Area of Science:
- Microbiology
- Structural Biology
- Toxicology
Background:
- Botulinum neurotoxins (BoNTs) are bacterial protein toxins from Clostridium species.
- Traditionally classified into seven serotypes (BoNT/A-G), genomic advancements reveal numerous subtypes and homologs, forming an expanding BoNT superfamily.
Purpose of the Study:
- To explore the expanding BoNT superfamily for novel therapeutic applications.
- To leverage structural insights for engineering BoNTs with enhanced efficacy and broader clinical use.
Main Methods:
- Analysis of recent structural studies on BoNTs, progenitor toxin complexes, and related toxins.
- Examination of toxin-receptor and toxin-substrate interactions.
- Genomic sequencing data analysis to identify novel BoNT-like toxins and homologs.
Main Results:
- Detailed mechanistic understanding of BoNT functions and variations derived from structural studies.
- Identification of a growing repertoire of BoNT superfamily members.
- Elucidation of the molecular basis for toxin diversity and function.
Conclusions:
- The expanding BoNT superfamily offers a rich resource for developing new therapeutic agents.
- Structural knowledge is crucial for engineering BoNTs to improve therapeutic outcomes and expand clinical applications.

01:26Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin
1.0K
Directly acting muscle relaxants like dantrolene and botulinum toxin (BoNT) have distinct mechanisms and applications. Dantrolene, a hydantoin derivative, acts on the ryanodine receptor (RYR1) in skeletal muscle cells. RYR1 are calcium channels present at the sarcoplasmic reticulum membrane. In response to excitation, they release calcium ions from the sarcoplasmic reticulum to the cytosol. Calcium promotes actin-myosin-mediated contraction of muscles.

3.1K
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

01:28Classification of Skeletal Muscle Relaxants
3.0K
Skeletal muscle relaxants are a group of drugs that can reduce muscle stiffness and induce temporary paralysis to relieve pain. These agents can act centrally to reduce muscle tone or spasms in painful conditions such as multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), or spinal injuries; they are called antispasmodics or spasmolytics.
Peripherally acting skeletal muscle relaxants interfere with the neurotransmission at the neuromuscular end plate to induce paralysis during...

01:29Indirect-Acting Cholinergic Agonists: Chemistry and Structure-Activity Relationship
856
Indirect-acting cholinergic agonists are agents that interact with the acetylcholinesterase enzyme in the synaptic cleft, preventing the breakdown of acetylcholine into choline and acetate. Consequently, the concentration of acetylcholine in the synaptic cleft increases. These agonists can be classified into reversible and irreversible inhibitors based on their duration of action.
Reversible inhibitors display short to medium durations of action. Short-acting agents include simple alcohols with...

01:30Classification of Neurotransmitters
4.9K
Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...

01:29Spasmolytic Agents: Chemical Classification
1.2K
Spasmolytic agents are drugs used to alleviate muscle spasms and spasticity. They can be categorized into different chemical groups based on their mechanisms of action. Centrally acting spasmolytics primarily affect the spinal cord, while others directly target skeletal muscle cells.
A major class of centrally acting spasmolytics is the α2-agonist, such as tizanidine. These drugs bind to α2-adrenoceptors, inhibiting the release of the excitatory neurotransmitter glutamate. They also...
