  • Patent number: 11638739
    Abstract: Peptides are provided consisting of L- and/or D-amino acids and combinations thereof, which affect myeloid cells by action on the triggering receptors expressed on myeloid cells (TREMs), including TREM-1 and TREM-2. The peptides act on the TREM/DAP-12 signaling complex. Also provided are lipid and sugar conjugated peptides comprising L- or D-amino acids. A method is provided of designing the peptides and lipid- and/or sugar-conjugated peptides comprising L- or D-amino acids. The disclosure relates to the therapy of various myeloid cell-related disease states involving the use of these peptides and compounds. The peptides and compounds are useful in the treatment and/or prevention of a disease or condition where myeloid cells are involved or recruited. The peptides of the present invention also are useful in the production of medical devices comprising peptide matrices (for example, medical implants and implantable devices).

  • Patent number: 10894098
    Abstract: A new approach to targeting imaging agents to macrophage-rich sites of interest is disclosed. Compositions of the invention are rHDL and HDL-like liposomal compositions, protein constituents of which, apolipoproteins A-I and/or A-II or fragments thereof are used not only as structural but also as targeting agents. This is achieved by certain controlled chemical or enzymatic modification of apolipoproteins A-I or A-II or fragments thereof. Such modification converts these apolipoproteins to substrates for macrophage scavenger receptors and results in the improvement of contrast agent-(HDL/modified apolipoprotein)-particle association with macrophages and/or absorption (uptake) by macrophages when compared to that of the contrast agent-(HDL/apolipoprotein)-particle constructed with non-modified naturally occurring apo A-I.

  • Patent number: 10538558
    Abstract: The present invention provides compositions comprising peptides derived from amino acid sequences (or from combinations thereof) of fusion and other protein regions of various viruses, including but not limited to, severe acute respiratory syndrome coronavirus, herpesvirus saimiri, human herpesvirus 6, Lassa virus, lymphocytic choriomeningitis virus, Mopeia virus, Tacaribe virus, Friend murine leukemia virus; human T lymphotropic virus type 1; herpesvirus ateles; Marburg virus; Sudan Ebola virus; Zaire Ebola virus, and comprising L- and/or D-amino acids and combinations thereof, which affect T cells by acting on the T cell antigen receptor (TCR). More specifically, the peptides act on the TCR??-CD3??-CD3??-?? signaling complex. Yet more specifically, the peptides act on the TCR?/CD3??/?? signaling module of TCR. The present invention further relates to the prevention and therapy of various T cell-related disease states involving the use of these compositions.
