Anthelminthic Agents

Anthelminthic Agents

Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...

Amebiasis

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...

Hormonal Regulation

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Regulation of Food Intake

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Neural Regulation

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Enteric Nervous System: Regulation of GI Motor Activity

Enteric Nervous System: Regulation of GI Motor Activity

The Enteric Nervous System (ENS) plays a pivotal role in regulating gastrointestinal or GI motor activity. This complex network of nerves, deeply embedded within the gut wall, responds to changes in the gut environment and receives input from both the autonomic nervous system and the central nervous system. By doing so, the ENS operates various programs tailored to the body's nutritional status and needs.
During periods of fasting, the ENS initiates the migrating myoelectric complex, a program...

Area of Science:

Comparative neurobiology of helminths
Neuropeptide signaling in invertebrates
Parasitology and drug discovery

Background:

Parasitic worms, including Nematoda and Platyhelminthes, possess complex nervous systems.
Neuropeptides are known to regulate vital physiological processes in these organisms.
Studies in model organisms like Caenorhabditis elegans and Schistosoma mansoni provide key insights.

Purpose of the Study:

To review the physiological roles of neuropeptides in both nematode and platyhelminth phyla.
To identify conserved and distinct functions of neuropeptides across these helminth groups.
To evaluate the potential of neuropeptides as therapeutic targets for parasitic worm infections.

Main Methods:

Review of existing physiological data on neuropeptide function in nematodes and platyhelminths.
Focus on well-studied neuropeptide families such as FMRFamide-like peptides (FLPs) and Insulin-like peptides (INSs).
Examination of neuropeptide-like proteins (NLPs) and neuropeptide Fs (NPFs) in platyhelminths.

Main Results:

FLPs significantly impact somatic and reproductive musculature, pharyngeal function, and motor neurons in nematodes.
INSs are crucial for nematode dauer formation and development.
FLPs excite somatic musculature in platyhelminths; NPFs inhibit cAMP accumulation in schistosomes.

Conclusions:

Neuropeptides play critical, conserved roles in the physiology of both free-living and parasitic helminths.
Neuropeptidergic signaling pathways offer a rich source of potential drug targets for treating helminth infections.
Further research into helminth neuropeptide biology is warranted for therapeutic development.
