Abstract: The invention relates to arenaviruses for use in the treatment and/or prevention of tumors and also a method for preparing arenaviruses with (improved) tumor-regressive properties.

Abstract: Provided are processes for the prevention or treatment of viral infection in a subject. Some aspects provide administration of a sphingoid compound, optionally sphingosine, an active ingredient that activates generation of a sphingoid base, optionally of sphingosine; or an active agent that inhibits the degradation of a sphingoid base, optionally of sphingosine, to a subject such as a human. By increasing the local concentration of sphingosine in a subject or an area of a subject to which the composition is administered such as the nose or interior of the nose or portion thereof, the ability of viruses to infect the subject or cells thereof is reduced thereby treating of preventing infection by the virus.

Abstract: The invention relates to arenaviruses for use in the treatment and/or prevention of tumors and also a method for preparing arenaviruses with (improved) tumor-regressive properties.

Abstract: An anti-CEACAM1 antibody includes at least one antibody heavy chain (VH) domain having antigen binding sites CDR1H, CDR2H and CDR3H, and at least one antibody light chain (VL) domain having antigen binding sites CDR1L, CDR2L and CDR3L. The antigen binding site CDR2H has a sequence homology of at least 80% to the amino acid sequence WINTYTGEPT (SEQ ID No. 21).
