Immortalized mammalian dendritic cell lines are provided that have characteristics of functional, mature dendritic cells; defined by surface phenotype, constitutive and inducible gene expression patterns and functional , effects on T lymphocytes. The cell lines are capable of continuous in vitro proliferation for extended periods of time. Of particular interest is the ability of the cell lines to present antigen in a stimulatory manner to naïve T cells. The dendritic cell lines are useful in gene discovery the generation , of dendritic cell subset-specific antibodies and probes; defining stages of dendritic cell differentiation and maturation; for induction of antigen specific …

Why it's free to use
- Filed December 7, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 7, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 7, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
