The present invention provides novel mammalian C-type lectin polypeptides associated with antigen presenting cells. Designated as Dendritic Cell C-type Lectins (DCL), the following four novel genes have been discovered: DCL 1, DCL 2, DCL 3 and DCL 4, as well as splice variants svDCL 2, svDCL 3 and svDCL 4, and a human homologue herein designated DCL 5. The present invention provides polynucleotides encoding DCL polypeptides, recombinant expression vectors, host cells transfected with the recombinant expression vectors, methods of producing and isolating the inventive polypeptides and various screening assays. Therapeutic compositions and methods of treating various diseases are also provided.

La présente invention concerne des nouveaux polypeptides de lectines de type C mammifères associés à des cellules présentatrices d'antigènes (CPA). On a découvert quatre nouveaux gènes désignés sous le nom de lectines de type C de cellules dendritiques (DCL), soit DCL 1, DCL 2, DCL 3 et DCL 4, de même que les variants d'épissage svDCL 2, svDCL 3 et svDCL 4 ainsi qu'un homologue humain appelé DCL 5. La présente invention concerne également des polynucléotides codant pour des polypeptides DCL, des vecteurs d'expression recombinants, des cellules hôtes transfectées avec ces vecteurs d'expression recombinants, des méthodes de production et d'isolement des polypeptides de l'invention, ainsi que diverses méthodes de criblage. L'invention se rapporte en outre à des compositions thérapeutiques ainsi qu'à des méthodes destinées à traiter diverses maladies.
