Helminth-derived proteins have immunomodulatory properties, influencing the host’s immune response as an adaptive strategy for helminth survival. Helminth-derived proteins modulate the immune response by inducing anti-inflammatory cytokines, promoting regulatory T-cell development, and ultimately favouring a Th2-biased immune response. This systematic review focused on helminth-derived proteins and explored their impact on reducing inflammatory responses in mouse models of colitis. A systematic search across Medline, EMBASE, Web of Science, and Cochrane Library identified fourteen relevant studies. These studies reported immunomodulatory changes, including increased production of anti-inflammatory cells and cytokines. In mouse models of colitis treated with on helminth-derived proteins, significant improvements in pathological parameters such as body weight, colon length, and microscopic inflammatory scores were observed compared to control groups. Moreover, helminth-derived proteins can enhance the function of Tregs and alleviate the severity of inflammatory conditions. The findings underscore the pivotal role of helminth-derived proteins in immunomodulation, specifically in the axis of cytokine secretion and immune cell polarization. The findings offer new opportunities for treating chronic inflammatory conditions such Crohn’s disease.

Brain metastasis is one of the major reasons of death in breast cancer (BC) patients, significantly affecting the quality of life, physical activity, and interdependence on several individuals. There is no clear evidence in scientific literature that depicts an exact mechanism relating to brain metastasis in BC patients. The tendency to develop breast cancer brain metastases (BCBMs) differs by the BC subtype, varying from almost half with triple-negative breast cancer (TNBC) (HER2⁻ ER⁻ PR⁻), one-third with HER2⁺ (human epidermal growth factor receptor 2-positive, and around one-tenth with luminal subclass (ER⁺ (estrogen positive) or PR⁺ (progesterone positive)) breast cancer. This review focuses on the molecular pathways as possible therapeutic targets of BCBMs and their potent drugs under different stages of clinical trial. In view of increased numbers of clinical trials and systemic studies, the scientific community is hopeful of unraveling the underlying mechanisms of BCBMs that will help in designing an effective treatment regimen with multiple molecular targets.

Most excitatory impulses received by neurons are mediated by ionotropic glutamate receptors (iGluRs). These receptors are located at the apex and play an important role in memory, neuronal development, and synaptic plasticity. These receptors are ligand-dependent ion channels that allow a wide range of cations to pass through. Glutamate, a neurotransmitter, activates three central ionotropic receptors: N-methyl-D-aspartic acid (NMDA), -amino-3-hydroxy-5-methylisoxazole-4-propionate (AMPA), and kainic acid (KA). According to the available research, excessive glutamate release causes neuronal cell death and promotes neurodegenerative disorders. Arabidopsis thaliana contains 20 glutamate receptor genes (AtGluR) comparable to the human ionotropic glutamate (iGluRs) receptor. Many studies have proved that AtGL-rec genes are involved in a number of plant growth and physiological activities, such as in the germination of seeds, roots, abiotic and biotic stress, and cell signaling, which clarify the place of these genes in plant biology. In spite of these, the iGluRs, Arabidopsis glutamate receptors (AtGluR), is associated with the ligand binding activity, which confirms the evolutionary relationship between animal and plant glutamate receptors. Along with the above activities, the impact of mammalian agonists and antagonists on Arabidopsis suggests a correlation between plant and animal glutamate receptors. In addition, these glutamate receptors (plant/animal) are being utilized for the early detection of neurogenerative diseases using the fluorescence resonance energy transfer (FRET) approach. However, a number of scientific laboratories and institutes are consistently working on glutamate receptors with different aspects. Currently, we are also focusing on Arabidopsis glutamate receptors. The current review is focused on updating knowledge on AtGluR genes, their evolution, functions, and expression, and as well as in comparison with iGluRs. Furthermore, a high throughput approach based on FRET nanosensors developed for understanding neurotransmitter signaling in animals and plants via glutamate receptors has been discussed. The updated information will aid in the future comprehension of the complex molecular dynamics of glutamate receptors and the exploration of new facts in plant/animal biology.

Vegetables are a crucial component of every diet and a good source of vitamins and minerals. Many raw vegetables, such as salads, are consumed, and consuming raw vegetables contaminated with human and animal feces can lead to a variety of intestinal parasite diseases. The goal of this cross-sectional study was to investigate the incidence of contamination of green leafy vegetables with human intestinal parasites, as well as identify the most common parasite species and any seasonal variation in parasite abundance in green leafy vegetables found and sold for human consumption in various markets and stores in Jeddah. To the best of our knowledge, no research has been conducted on the prevalence of parasite-contaminated vegetables in Jeddah. From September 2020 to July 2021, 250 leafy vegetables (coriander, watercress, lettuce, parsley, leek, and green onion) were collected from various markets and stores in Jeddah. The vegetables were sorted, labelled, and evaluated in the laboratory after being completely washed with distilled water, examined for sediment, staining, and microscopically examined. Chromatographic immunoassay tests were also used to confirm parasite identification. Intestinal parasites were discovered in 35.2% of the vegetables (88/250). Coriander was the most contaminated (64.2%), while green onion was the least contaminated (21.9%). Blastocystis spp. was the most often discovered parasite (55.7%), followed by Strongyloides spp. larva (22.7%) and Entamoeba coli cysts (6.8%). Summer has the greatest percentage of parasites, followed by autumn, while winter has the fewest. There was no statistically significant relationship between the kind of vegetable, seasonal parasite prevalence in green vegetables, and parasite type.These findings highlight the importance of inspecting vegetables grown or imported from endemic countries for parasite contamination. In Jeddah, several fresh green vegetables were tainted with intestinal parasites. This demonstrates that those who consume raw vegetables regularly may be susceptible to parasitic illnesses. These findings highlight the need of monitoring vegetables grown or imported from parasitic-endemic areas. As a result, it is critical to establish strategies and control measures to limit the likelihood of parasites in food-borne diseases.Keywords: contamination; intestinal parasites; Jeddah; leafy vegetables
