Abstract:
Fungal infections pose a significant global health threat with rising morbidity and mortality rates. However, the repertoire of effective antifungal drugs remains narrow, a challenge that is further exacerbated by the increasing emergence of (multi)drug-resistant strains. This underscores the urgent need for novel therapeutic strategies. Among them, antifungal peptides (AFPs) have emerged as a promising alternative. AFPs are small, naturally occurring peptides produced by a wide range of organisms, including plants, animals, fungi, and bacteria, as part of their innate immune defense. In addition, synthetic and semisynthetic variants have also been engineered. We here underscore the potential of AFPs as viable candidates for the development of next-generation antifungal therapies. In particular, we advocate their multimodal advantage that spans beyond standalone activity, including their synergistic and immune-regulatory potential.

01:23Propagation of Action Potentials
Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions. When a stimulus, like a touch or a signal from another neuron, triggers the neuron, sodium channels open, allowing sodium ions to...

Resting Phase:
In this phase, the cell's membrane is at its resting potential, typically around -70 millivolts (mV) for neurons. Inside the cell, there is a higher concentration of potassium ions (K+) and a lower concentration of sodium ions (Na+). Voltage-gated sodium channels are closed, and...
