Salt Lake City, Utah and Los Angeles, CA – December 19th, 2017 (PRBUZZ) — Leonhardt’s Launchpads, an organ regeneration innovation/startup accelerator, focused on developing novel therapeutics for the treatment of organ degeneration today announced that it has filed a new patent application for the controlled up or down regulation of CXCL5 expression. CXCL5 is a protein known from previous pre-clinical studies to have a role in preventing artery occlusion and cancer tumor growth as well as many other potential useful therapeutic applications including the treatment of arthritis. This patent will be sub-licensed exclusively organ by organ to up to 27 unique organ regeneration focused startups within the Leonhardt’s Launchpads innovation accelerators in Utah and California including CancerCell, PancreaCell, DentaCell Accelerator, LiverCell, BioLeonhardt and VascuStim.
Function
The protein encoded by this gene, CXCL5 is a small cytokine belonging to the CXC chemokine family that is also known as epithelial-derived neutrophil-activating peptide 78 (ENA-78). It is produced following stimulation of cells with the inflammatory cytokines interleukin-1or tumor necrosis factor-alpha. Expression of CXCL5 has also been observed in eosinophils, and can be inhibited with the type II interferon IFN-γ. This chemokine stimulates the chemotaxis of neutrophils possessing angiogenic properties. It elicits these effects by interacting with the cell surface chemokine receptor CXCR2. The gene for CXCL5 is encoded on four exons and is located on human chromosome 4 amongst several other CXC chemokine genes. CXCL5 has been implicated in connective tissue remodeling. CXCL5 has been also described to regulate neutrophil homeostasis.
Clinical significance
CXCL5 plays a role in reducing sensitivity to sunburn pain in some subjects, and is a “potential target which can be utilized to understand more about pain in other inflammatory conditions like arthritis and cystitis.”. CXCL5 is well known to have chemotactic and activating functions on neutrophil, mainly during acute inflammatory responses. However CXCL5 expression is also higher in artherosclerosis (a chronic inflammatory condition) but is not associated with neutrophil infiltration. Instead CXCL5 has a protective role in atherosclerosis by directly controlling macrophage foam cell formation.
“We targeted the discovery search for the precise bioelectric signals and sequence for triggering CXCL5 expression control up and down on demand from tissues more than 7 years ago and we are delighted to finally hit on it. This adds to our building library of over a nineteen bioelectric stimulation signals for promoting organ regeneration and cancer tumor treatment. We believe this combined with our programmable micro-infusion pump and fifteen component organ regeneration composition puts our team in a leadership position to in the near future to potentially help patients with degenerating and diseased organs to recover.” Dr. Jorge Genovese, VP of Bioelectric Regeneration Research at Leonhardt’s Launchpads
The Leonhardt-Genovese team working in collaboration with component suppliers has developed both wireless non-invasive and implantable wire lead based means to get their bioelectric signals intended for regeneration and healing or cancer recovery to organs.
The bioelectric stimulation signals for controlling up or down regulation of CXCL5 are licensed exclusively organ by organ without additional fees or royalties to organ specific portfolio startups within the Leonhardt’s Launchpads innovation and startup accelerator(s) as per the terms of accelerator participation.

“The CXCL5 protein was found in previous pre-clinical studies to be a key cytokine in potentially reducing risk of heart attacks, strokes and limb amputations due to atherosclerosis and resulting artery occlusion. Control of CXCL5 expression has also been suggested from data gathered in numerous studies as a possible means to stop cancer tumor growth. We are delighted to be adding bioelectric up or down regulation control of CXCL5 to our armamentarium of technologies for organ regeneration and recovery.” states Howard Leonhardt, co-Inventor, Executive Chairman & CEO of Leonhardt’s Launchpads
“CXCL5 is one of the most potent cytokines known to reduce risk of arterial occlusion that is a primary cause of heart attacks and stroke as well as lower limb ischemia. Numerous studies have demonstrated that controlled downregulation of CXCL5 can be antii-angiogenic and thus help starve cancer tumors of blood supply. We are proud to have extended our portfolio of bioelectrical stimulation signals to include CXCL5. We are embarking upon well controlled translational research studies to prove our combination therapy out for regenerative repair and recovery of a number of organs including those that may be ravaged with cancer tumors.” states Dr. Leslie Miller, Chief Medical Officer of Leonhardt’s Launchpads

“Elevated levels of CXCL5 are found in patients with fast growing cancer tumors. A number of small animal studies have confirmed that down regulation or inhibition of CXCL5 can serve to help reduce or stop cancer tumor growth especially in combination with other cancer therapies. We look forward to exploring for the first time the real time monitoring and controlled regulation of CXCL5 with specific bioelectric signals as described in these patent claims pending. Control of the expression of this specific cytokine can be incorporated into a overall real time inflammation monitoring and control protocol with other bioelectric signals directed towards inflammation control and organ recovery.” stated Dr. Santosh Kesari, Director of Research, Pacific Neurosciences Institute and John Wayne Cancer Institute, Santa Monica, California and Chief Advisor for CerebraCell and CancerCell two startups in the Leonhardt’s Launchpads innovation and startup accelerator.
