Several studies indicate various pharmacological and therapeutic effects of peroxisome proliferator-activated receptors (PPARs) in different disorders. The current review describes the influences of PPARs on respiratory, allergic, and immunologic diseases. Various databases, including PubMed, Science Direct, and Scopus, were searched regarding the effect of PPARs on respiratory and allergic disorders from 1990 to 2024.

Article Synopsis
  • - Paraquat (PQ) is a toxic herbicide that can cause serious lung issues, but Crocus sativus (Cs) has shown promise for treating related respiratory problems due to its anti-inflammatory and antioxidant properties.
  • - This study aimed to assess how Cs extract and pioglitazone (Pio) can prevent lung damage and inflammation caused by PQ exposure in rats, comparing their effects to dexamethasone (Dexa).
  • - Results indicated that treatments with both Cs and Pio improved lung health and function, with the combination showing the most significant benefits, suggesting Cs could be a viable alternative to traditional treatments like Dexa.

Objectives: In the present study, the relaxant effect of crocetin on tracheal smooth muscle cells (TSM) and its possible mechanisms were evaluated.

Materials And Methods: The study was conducted on 54 male Wistar rats in 8 groups. TSM was contracted by methacholine (10 μM) and KCl (60 mM), and the relaxant effects of four cumulative concentrations of crocetin, petal extract of saffron, and theophylline were examined on non-incubated and TSM incubated with propranolol, chlorpheniramine, diltiazem, atropine, glibenclamide, and indomethacin were investigated.

One of the main causes of death on the globe is cancer. Peroxisome-proliferator-activated receptors (PPARs) are nuclear hormone receptors, including PPARα, PPARδ and PPARγ, which are important in regulating cancer cell proliferation, survival, apoptosis, and tumor growth. Activation of PPARs by endogenous or synthetic compounds regulates tumor progression in various tissues.

Camel milk (CM) has been found to have several health benefits, including antiviral, antibacterial, anti-tumor, anti-fungal, antioxidant, hypoglycaemic and anti-cancer activities. In addition, CM can counter signs of aging and may be a useful naturopathic treatment for autoimmune diseases. The composition of CM varies with geographic origin, feeding conditions, seasonal and physiological changes, genetics and camel health status.
