Gene-modified, inflammation-specific monocytes that comprise a 1-alpha-hydroxylase gene, where the 1-alpha-hydroxylase gene is expressed to produce functional 1-alpha-hydroxylase enzyme when the monocytes transdifferentiate into gene-modified, inflammation-specific macrophages. Gene-modified, inflammation-specific macrophages that comprise a 1-alpha-hydroxylase gene. A method for treating one or more than one inflammation-related condition or disease, the method comprising administering gene-modified, inflammation-specific monocytes that comprise a 1-alpha-hydroxylase gene, where the 1-alpha-hydroxylase gene is expressed to produce functional 1-alpha-hydroxylase enzyme when the monocytes transdifferentiate into gene-modified, inflammation-specific macrophages.
