For years, Dan and Terri DeNeui, together with EVEXIAS Health Solutions and FarmaKeio, have been leading the fight for evidence-based medicine, patient choice, and responsible access to innovative therapies
Specifically, one SCFA, propionate, has protective effects on the integrity of the BBB and protection of tight junction proteins [146]

Furthermore, MMP-9 is elevated in the skin and plasma of patients with common vitiligo, being produced in keratinocytes by the stimulation of TNF and IFN and associated with E-cadherin cleavage.44 The DKK1 protein, which reduces melanogenesis and certain somatic functions of melanocytes, is overexpressed by lesional fibroblasts in vitiligo.45 Similarly, there is a greater expression of fibronectin, a key protein in intercellular communication by binding to integrins, in the dermis of patients with vitiligo compared with healthy controls.43 Additionally, elastin is reduced in lesional dermis, but collagen fibers show no difference when compared to unaffected skin.46 Oxidative changes Cutaneous melanocytes, located in the organ with the greatest interface with the external environment and, consequently, the most exposed to ultraviolet radiation and pollutants, are particularly vulnerable to excessive production of reactive oxygen species (ROS)

There are lots of others, with names like TB-4, TB-500, CJC-1295, ipamorelin, tesamorelin, and GHK-Cu
This aligns with the broader trend of exploring natural bioactive compounds for asthma management, as with other phytoconstituents such as Pycnogenol and grape seed proanthocyanidin extract, which also exhibit anti-inflammatory and antioxidant effects [183, 184]
