• More info on RP trials requested
• Posted: 2007-08-08 07:18:06 By Mini S
• Hi,
  
  Can someone please give me info on the following:
  
  1. Where do I find more information about the CNTF trials and results?
  2. Does the implant regenerate dead photoreceptors?
  3. Does the implant help restore lost vision?
  4. Are there any trials going on for humans on stem cell transplantation method?
  
  Thanks and regards,
  Mini

• Anyone from San Francisco, CA wanna talk about there RP
• Posted: 2007-08-07 19:13:12 By Jordan C
• I am a 36 y/o male in San Francisco. I was diagnosed when I was 15. I would like to talk to other RP people so I can get a better idea of what to expect. I can still drive in the day and have some problems in the dark, but at night forget it. I gave up going to the doctors because I felt like I was just a ginne pig. All I want to do is meet people like me and talk. Anyone interested? Jordan

• Still looking for late stage RP subjects in Dallas
• Posted: 2007-08-07 16:27:55 By Marisa P
• I figured I didn't qualify for the ongoing trials, but I thought I'd try. I just heard the official confirmation, at 20/30 my visual acuity is too good for the late stages although I am legally blind! They also said that they are still looking for subjects for the trial. Visual acuity must be between 20/80 and 20/320. Anyone ready for this one? Interestingly, I had cataract surgery and that in itself didn't keep me out. I guess it's best to contact the appropraite center if you are interested and had cataract surgery.
  Good luck to all you lucky ones.

• Macular Hole Surgery
• Posted: 2007-08-06 14:20:06 By Reyne K
• I noticed that I had a blind spot in my central vision and didn't think it was the RP affecting my macula already. After having an OCT and an angiogram, a macular hole was confirmed. I will be off to the Wills Eye Center in Philadelphia for the vitrectomy surgery. Has anyone had this done? They don't want to combine the cataract surgery with this. I am really interested in the recovery afterwards.

• ECT-CNTF does this will stop the degeneration of the RETINITIS PIGMENTOSA?
  
  and how long the effectiveness of this CNTF?
  Do they run out?
  
  How do i know if my RP is late or early stage?
  
  My vision has tiny viens and arteries floating on on my eyesight, does CNTF can remove these? and what are these floating arteries and viens called?
  
  Thanks in advance.

  Treatment of Damaged Retinas: New Drugs on the Horizon?
  
  
  Filed under: Ophthalmology
  Medgadget.com - San Francisco,CA,USA
  Friday, August 3, 2007
  
  
  Scientists from the RIKEN Research Institute and Kyoto University in Japan
  are reporting that when they stimulated a specific biochemical pathway they
  achieved retinal regeneration in a rat model:
  
  It is a discovery that may ultimately lead to new therapies for retinal
  diseases including the degenerative disease called retinitis pigmentosa.
  
  Previous research by the team led by Masayo Takahashi at the RIKEN Center
  for Developmental Biology, Kobe, demonstrated that retinal support cells
  called Muller glia could de-differentiate to assume a neuronal fate, but the
  level of regeneration via this mechanism was very low, occurring in just a
  few cells.
  
  But the new study, published recently in the Journal of Neuroscience,
  indicates that retinal cell regeneration in an in vitro model of retinal
  damage can be increased by as much as twenty-fold in the presence of the
  protein Wnt3a.
  
  The researchers initially performed experiments in cultured retinas isolated
  from rats. When they administered Wnt3a, they found a significant increase
  in proliferation of neuronal progenitors from the de-differentiated cells...
  
  "Newly generated cells constituted almost a layer of cells in the outer
  nuclear layer in the retinal degeneration model mice," says Takahashi. "We
  only observed several cells per field without Wnt treatment. Furthermore,
  the retinal neurons were regenerated all over the retina."
  
  The regenerated cells migrated to the outer nuclear layer of the retina,
  where, in the presence of retinoic acid (a form of vitamin A) or valproic
  acid, the team observed differentiation into rod photoreceptor cells.
  
  The phenomenon appears to involve the canonical Wnt signaling pathway, in
  which Wnt activation protects the â-catenin protein from degradation,
  allowing it to accumulate in the nucleus where it regulates gene
  transcription. The process could also be stimulated with small molecule
  inhibitors of glycogen synthase kinase-3â, which normally blocks activation
  of the pathway.
  
  Treatment of retinas isolated from a murine model of retinitis pigmentosa
  with Wnt3a similarly resulted in the regeneration of retinal cells,
  suggesting that the Wnt/â-catenin signaling pathway contributes to central
  nervous system regeneration.

• Posted: 2007-08-03 18:09:30 By carolina s
• Hello
  I came back from my post- op follow up for the CNTF implant and the shared with me that from the 3 people recruited I was the only one to go though with it. The 2 people that had qualified, after all the intense testing etc. decided to back up right before schedulling surgery. The Dr was a bit upset about this, since she believes they took the spot from some other candidates that really wanted the surgery. SOOOOO.....there maybe one more last minute opening for the CNTF implant at Bascom Palmer.
  I can tell you that 3 days after my surgery I am doing SUPER !!!! very little discomfort and my Dr is very pleased with my outcome.
  cheers

• RP Center to Open In India

• On April 12, 2007, Stem Cell Pharma Inc. (SCPI) USA and King Multitech Global Pvt LImited (KMT) India announced the signing of a Joint Venture (JV) by which a Retinitis Pigmentosa Center, a first of this type in the world, will open September of 2007 in Ludhiana, Punjab, India.
  This center would accommodate initially 10 patients a day, or up to 300 patients a month, at prices close to ones paid to SCPI; i.e. $8,000 per patient. India has a population of 400,000 patients with RP, a disease which had no treatment until now.

  LONDON (Reuters) - The ability of zebrafish to regenerate damaged retinas has given scientists a clue about restoring human vision and could lead to an experimental treatment for blindness within five years.
  
  ADVERTISEMENT
  
  British researchers said on Wednesday they had successfully grown in the laboratory a type of adult stem cell found in the eyes of both fish and mammals that develops into neurons in the retina.
  
  In future, these cells could be injected into the eye as a treatment for diseases such as macular degeneration, glaucoma and diabetes-related blindness, according to Astrid Limb of University College London's (UCL) Institute of Ophthalmology.
  
  Damage to the retina -- the part of the eye that sends messages to the brain -- is responsible for most cases of sight loss.
  
  "Our findings have enormous potential," Limb said. "It could help in all diseases where the neurons are damaged, which is basically nearly every disease of the eye."
  
  Limb and her colleagues studied so-called Mueller glial cells in the eyes of people aged from 18 months to 91 years and found they were able to develop them into all types of neurons found in the retina.
  
  They were also able to grow them easily in the lab, they reported in the journal Stem Cells.
  
  The cells have already been tested in rats with diseased retinas, where they successfully migrated into the retina and took on the characteristics of the surrounding neurons. Now the team is working on the same approach in humans.
  
  "We very much hope that we could do autologous transplants within five years," Limb told Reuters.
  
  Autologous transplants, initially on a trial basis, will involve manipulating cells and injecting them back into an individual's own eye. Eventually, Limb hopes it will also be possible to transfer the cells between different people.
  
  "Because they are so easy to grow, we could make stem cell banks and have cell lines available to the general population, subject to typing as with blood transfusions," she said.
  
  Just why zebrafish have an abundant supply of adult stem cells to regenerate their retinas, while they are rare in mammals, remains a mystery but Limb suspects it is because mammals have a limiting system to stop proliferation.
  
  The new work on Mueller glial cells is the latest example of researchers exploring the potential of different kinds of stem cells in treating eye disease. Another team from UCL and Moorfield's Eye Hospital said in June they aimed to repair damaged retinas with cells derived from embryonic stem cells.
