I am unable to create a summary of the requested article because the search results provided do not contain the article titled "MSD and Quotient collaborate on IBD drug targets" or its content. The search results contain information about IBD (idiopathic intestinal inflammation) in the Czech and Slovak context, including information about treatment, patient organizations and conferences, but not about the specific collaboration between MSD and Quotient Therapeutics on the discovery of new IBD drug targets. In order to create an accurate and factual summary as per your requirements, I need access to the article itself.
