The invention involves a method for modulating leukocyte activity, comprising delivering to a leukocyte a vector containing nucleic acid molecule(s), whereby the leukocyte contains Cas9 and the vector expresses one or more RNAs to guide the Cas9 to introduce mutations in one or more target genetic loci in the leukocyte, thereby modulating expression of one or more genes expressed in the leukocyte. The invention also involves identifying genes associated with leukocyte responses and experimental modeling of aberrant leukocyte activation and diseases associated with leukocytes by introducing mutations into leukocytes. The invention comprehends testing putative treatments with such models, e.g., testing putative chemical compounds that may be pharmaceutically relevant for treatment or gene therapy that may be relevant for treatment, or combinations thereof. The invention allows for the study of genetic diseases and putative treatments to better understand and alleviate leukocyte associated diseases.

The present invention is directed to compositions and methods for modulating c-Rel-dependent cytokine production without materially altering the level of expression of NFκB and/or the amount of IκB. The present invention is also directed to screening for modulators of c-Rel activity as determined by assaying for altered subcellular localization of c-Rel but where the level of expression of NFκB and/or the amount of IκB is materially unaltered.

Mutations in keratin genes or the genes that regulate keratin expression can result in epithelial cells lacking sufficient structural integrity. The resulting disruption of connective tissue gives rise to inherited disorders such epidermolysis bullosa. It has been found that various cannabinoids (including mixtures of cannabidiols and cannabinol) upregulate expression of various keratins such that loss of function in other keratin genes may be compensated for. By way of this upregulation, these cannabinoids can be used to treat epidermolysis bullosa and other connective tissue disorders arising from intermediate filament dysfunction.
