Our microbiome and its link with treatment for Pernicious Anaemia

More
Professor Martin Warren is a research scientist with a strong background interest in a group of molecules called the pigments of life. These molecules include haem, which give blood its red colour, chlorophyll, which gives grass its colour, and vitamin B12, the antipernicious anaemia factor. Of all these molecules vitamin B12 is the most fascinating. Interestingly, vitamin B12 is only made by certain bacteria and a significant part of the Warren research laboratory is dedicated to understanding how the molecule is made and how it works it way into the foodchain and how the vitamin can be made more bioavailable.

In Vitro Gastric Inflammation, B12 and Treatment
More
Dr Anna Guildford is a Tissue Engineer and Biomaterial Scientist. Her work is based on increasing our scientific knowledge of B12 and understanding the personalised nature of the varied and wide ranging symptoms associated with its deficiency. Longer term her aim is to develop a degradable implant to deliver a constant and optimal dose of B12 mimicking the dietary intake of non-sufferers. Her current work is focused on the development of models of the disease using cells from the stomach lining and inflammatory and nerve systems to identify the optimal dosage and optimal type of B12 for each cells individual purpose.
