A protein called IRHOM2 has been identified as a possible new target for drugs aimed at treating RA, and could be useful for those who do not respond to anti-TNFs or even eventually replace anti-TNFs altogether. The full article on IRHOM2 can be found here, but here’s a short summary.
TNF or tumour necrosis factor has a useful purpose in the body; it is a signalling protein and it signals the body to produce a protective inflammatory response. Thus if a part of you is infected, TNF starts the process of inflammation, which takes immune response cells to the appropriate area in the blood, and they start to attack the disease-causers. In this case inflammation is a good thing.
However, when too much TNF is produced, immune cells start to act on things they shouldn’t, like our joints – leading to RA.
Anti-TNFs attack TNFs directly, and do a mighty fine job for many people, but they are toxic and can have nasty side effects.
IRHOM2 is a protein that helps to release TNF from where it sits harmlessly and inactively on the surface of cells, so attacking IRHOM2 should have the same effect as attacking TNF – reducing in TNF release and therefore reduction in inappropriately active immune cells, and so reduction in RA symptoms.
It is hoped that drugs targeting IRHOM2 would be less toxic, because they will only block TNF release from the specific cells that contribute to joint damage, and they could be an alternative for those who don’t respond well to anti-TNFs.
There is, of course, a long way to go. This is just the identification of a possible target. The next step is to find something that will actually block IRHOM2 and be safe to use in patients. Then there will be the long, slow plod (quite necessary for safety reasons!) through clinical trials, with no doubt a few failures along the way – but some years down the line this could be a real breakthrough. Let’s hope so!
p.s. I do hope this makes sense! I’m really, really tired and I haven’t had hubby proofread it yet!

Well, all those of us who suffer from RA and/or are women will already know that it’s not because we’re a bunch of winging Minnies, but until recently, although a genetic link was suspected, it had not been found.
Professor Alan Silman, medical director of Arthritis Research UK, said: ‘This is the first time that a genetic association has been established between rheumatoid arthritis and the X chromosome. This could provide a useful clue in helping us to understand why rheumatoid arthritis is three times more likely to occur in women.’
It was reported late last year that among the 46(!) genes that seem to be linked to people getting RA, some have recently been discovered that are on the X chromosome. Now both men and women have X chromosomes, but while women have two X chromosomes, men have one X and one Y chromosome instead, and the genes don’t occur on the Y.
This is all part of a long-term study from the University of Manchester (UK) and the genes on the X chromosome are among the 14 found towards the end of last year.
Professor Jane Worthington, study lead based at the NIHR Manchester Musculoskeletal Biomedical Research Unit, said: ‘This groundbreaking study brought together scientists from around the world and involved the use of DNA samples from more than 27,000 patients with rheumatoid arthritis and healthy controls’ She added, ‘We observed remarkable similarities with genetic markers associated with other autoimmune diseases,’ which is an interesting, but perhaps unsurprising finding.
The intention behind all this work is that it will lead to new ‘genetic therapies’ – drugs that can target certain genes and switch them on/off as appropriate. Let’s hope they won’t be too long in coming!

Good news – there’s a rheumatoid arthritis blog currently in the top FIVE of the Healthline blog awards. The bad news? Well, I could say, ‘It’s not me’ but hey, I post a few times a year and witter on about biscuit making, so I think Kelly at Rheumatoid Arthritis Warrior, who really does work at making an informative and blog for suffers, and increasing awareness of RA, deserves the kudos more; no, the bad news is it’s not number one … yet. So please do go and vote for her!
And do bear in mind that while you’re at it, you can vote for me too … and all my online ‘mates': Wren and Andrew and Carla and all the folks in my blog roll; because you can vote for as many people as you like each day, although you can only vote for an individual once a day!
And if you have an RA blog with a handful of votes, like me, and you know you’re never going to get to where RA Warrior is, why not get behind her as well and get your readers voting for her … or her and you! :-)

Today was my first day back at work – knee flare seemed to be pretty much over: the swelling had gone right down, it didn’t feel terribly hot, but it was achy now and then. Hurrah.
However, now the other knee had started to ache – RA, or just a reaction to me walking ‘funny’ because of the left knee flaring? I don’t know – but to add to the mix, today being my first day back at work meant it was also the first day since the holidays where I haven’t spent a significant amount of time with my feet up – and I’m really feeling that this evening, as I sit here typing with an ice pack clamped between my knees, and the heat pack waiting for me in bed!
Here’s the thing though – we’re moving offices tomorrow!
Fortunately hubby has the day off and has been volunteered, slightly unwillingly but with good grace, to be my feet, and the facilities manager in the building is also going to help us lug stuff, and then my two colleagues are both fairly fit … so hopefully I can pull out a conductor’s baton from somewhere and just direct operations!
