In the peripheral nervous system, toxins can affect the physiological functions of neurons themselves or interfere with the synaptic signaling processes. As the somatic nervous system is essential for the activation of respiratory muscles, most neurotoxins appear to affect its function rather than that ...
—How do brain cells send messages? However, Kipnis told Live Science that an experimental method used in that study may itself affect glymphatic flow, muddying the results. In addition, he said many scientists agree that this waste clearance is most efficient during sleep. Nedergaard added tha...
How Environmental Toxins Affect Your Hormonal Health (+ Ways to Limit Your Exposure)Has it ever crossed your mind that the air you breathe or the cookware you use for your meal prep can cause your endocrine system to go haywire? Every day, we’re exposed to countless sources of ...

The scorpion toxins can be divided into: 1) "long chain toxins" (60-70 amino acids residues cross-linked by 4 disulfide bridges) that affect exclusively voltage-dependent Na+ channels of excitable cells; 2) "short chain toxins" (30-40 amino acids residues cross-linked by 3 disulfide ...
The venom of the spider Phoneutria nigriventer contains a mixture of toxins that affect ion channel function, decreasing neuronal cell death and ameliorating neurotransmission alterations. The PhTx3-1 toxin is capable of blocking transient outward K+ currents (KvIA), improving ...

The accumulation of uremic solutes in the blood and the brain may affect cognitive function6. Uremic toxins are classified into three groups based on their protein binding property and molecular weight: protein-bound solutes, middle molecules, and small water-soluble solutes7. Although hemodialysis (...
Notably, there were no histologically observed brain microthrombi, vessel occlusions or evidence of ischemia [74]. How then did the patients develop neurological symptoms, and was Stx to blame? One study in rats has shown that Stx1 effect on astrocytes could indirectly affect t...
TE-671 cells, and assessed peptide activity in CHO cells expressing NaV1.7 and the NaVβ1-β4 subunits. However, although successful transfection with β subunits was confirmed by the presence of the transfection marker GFP, ExTxA did not affect inactivation of NaV1.7-mediated currents in the ...
