Telomere length and the common cold

IAS News 21 February 2013 | 4 Comments

Telomeres are the caps on the end of chromosomses that get shorter each time a cell divides, up until the point where the cell simply fails to function anymore and dies off. These telomeres are the topic of much research as many researchers have linked the lengths of them to chances of living longer – which of course makes sense. The longer your telomeres the more times they will be able to divide before killing the cell off.

In research carried out by Vanderbilt University Medical Center in Nashville by a professor James Crowe, he found that adults with shorter telomeres were more likely to become infected with colds. In order to get an accurate reading from all the 152 adults in the study, they were all deliberately exposed to the cold virus. Results were then taken from the numbers which suffered from the cold in order to take note of how effective their immune system was. 69% of those in the study were infected by the cold, and 22% of this number got sick.

In terms of telomeres the rate of sickness varied greatly depending on the length of these end caps which hold the DNA within chromosomes. 26% of the volunteers who had the shortest telomeres got sick, as opposed to only 13% of those who had the longest telomeres.

This recent study was looking at telomere lengths in younger people; the age range for the study was between the ages of 18 to 55. As opposed to previous studies focusing on those older than 55 where results showed the risk of heart disease, cancer and infections were looked into. Previous studies have also shown that telomeres lengths don’t tend to change much over 10 years.

One question that this study hasn’t answered is why telomeres shorten. Previous studies have shown that early life maltreatment, smoking, radiation, or psychologlical stress may be linked to the shortening of these end caps. IAS sells TA65 in both 90 caps and 30 caps pack size which have been proven to lengthen telomeres.

  1. I noticed in the article that telomere length doesn’t tend to change much over ten years. I am curious if taking TA65 has been proven to lengthen telomeres and what kind of test is required to determine baseline?

    • IAS says:

      TA65 seeks out the shortest telomeres and adds length to these. This then has a knock on effect on the average length of all the telomeres. This is where the positives come into this product. As you get older the telomeres get due to the faster cell division, meaning it is more necessary to increase the length of the shortest. Younger people which this article looked at more don’t have so many isses in shortening telomeres as they are still quite long. I hope this clears up any confusion, more information can be found on our TA65 webpage

    Are you saying that taking TA65 after the age of 55 does little or no good?
