  • Publication number: 20220023401
    Abstract: The present disclosure is directed to individual A? peptide immunogen constructs, peptide compositions comprising these A? peptide immunogen constructs and mixtures thereof, pharmaceutical compositions including vaccine formulations comprising these A? peptide immunogen constructs, with the individual A? peptide immunogen constructs having the N-terminus of the A? peptide as the B cell (B) epitopes linked through spacer residue(s) to heterologous T helper cell (Th) epitopes derived from pathogen proteins that act together to stimulate the generation of highly specific antibodies directed against the N-terminus of the A? peptide offering protective immune responses to patients at risk for, or with, Alzheimer's Disease.

  • Publication number: 20220023400
    Abstract: The present invention is directed to novel heterologous promiscuous and artificial T helper cell epitopes (Th epitopes) designed to provide optimum immunogenicity of a target antigenic site. The disclosed Th epitopes, when covalently linked to a B cell epitope in a peptide immunogen construct, elicit a strong antibody response to the B cell epitope of the target antigenic site. The Th epitopes are immunosilent on their own, i.e., little, if any, of the antibodies generated by the peptide immunogen constructs will be directed towards the Th epitope, thus allowing a very focused immune response directed to the targeted antigenic site. The heterologous promiscuous Th epitopes provide effective and safe peptide immunogens that do not generate inflammatory, anti-self, cell-mediated immune responses following administration.

  • Patent number: 11180555
    Abstract: The present disclosure is directed to antibodies directed against CD4, compositions thereof, and methods employing such compositions for the prevention, treatment, and/or functional cure of HIV infection. The disclosed antibodies exert potent competitive HIV entry inhibition by binding to domain 1 of CD4 in both cell-free and cell-to-cell systems. The disclosed antibodies also inhibit antigen induced T cell proliferation and cytokine production (IL2 and IFN-gamma) of CD4+ T cells, which is implicated in the pathogenic cycle of pyroptosis. The disclosed antibodies also have the ability to reactivate resting CD4+ T cells, which is particularly useful for reactivating latent reservoirs of HIV in resting T cells to make these cells susceptible to treatment with antiretroviral agents. Reactivation of HIV infected resting CD4+ T cells allows combinational treatment incorporating antibodies of the current invention with HAART in HIV infected patients leading to the functional cure of HIV.

  • Publication number: 20210347866
    Abstract: The present disclosure is directed to dipeptide repeat (DPR) peptide immunogen constructs, compositions containing the constructs, antibodies elicited by the constructs, and methods for making and using the constructs and compositions thereof. The disclosed DPR peptide immunogen constructs contain a B cell epitope derived from a DPR protein from C9orf72, including repeats of poly-GA, poly-GP, poly-GR, poly-PR, and poly-PA, linked to a heterologous T helper cell (Th) epitope directly or through an optional heterologous spacer. The B cell epitope portion of the peptide immunogen constructs contain about 10 to about 25 repeats of the respective dipeptide sequence. The disclosed peptide immunogen constructs stimulate the generation of highly specific antibodies directed against the DPR sequences.

  • Patent number: 11017634
    Abstract: The present invention is to determine whether a game result of a slot machine satisfies a specified condition by using a control unit, the specified condition is defined as any one of the plurality of game symbols in the game result replaced so that the reward condition is satisfied, and one of the game symbols replaced to be located at a replacement position; when the control unit determines that the game result satisfies the specified condition, the control unit activates a three-dimensional re-spinning component to generate a replacement game symbol. The replacement game symbol is used to replace the game symbol at the replacement position and update the game result, thereby the control unit re-determines whether the updated game result meets the reward condition, and after the reward condition is met, performs a reward program by using a reward unit.

  • Publication number: 20210138049
    Abstract: The present disclosure is directed to alpha-synuclein (?-Syn) peptide immunogen constructs, compositions containing the constructs, antibodies elicited by the constructs, and methods for making and using the constructs and compositions thereof. The disclosed ?-Syn peptide immunogen constructs contain a B cell epitope from ?-Syn linked to a heterologous T helper cell (Th) epitope directly or through an optional heterologous spacer. The B cell epitope portion of the peptide immunogen constructs contain about 10 to about 25 amino acid residues of ?-Syn, corresponding to the sequence from about the Glycine at position 111 (G111) to about the Asparagine at position 135 (D135) of full-length ?-Syn. The ?-Syn peptide immunogen constructs stimulate the generation of highly specific antibodies that are cross-reactive with the ?-sheet of ?-Syn as monomers, oligomers, and fibrils, but not the natural ?-helix of ?-Syn, offering therapeutic immune responses to hosts at risk for synucleinopathies.

  • Patent number: 10818136
    Abstract: The present invention relates to a game system allowing at least one prize money value to correspond to at least one optional betting option respectively. After a player bets on the at least one optional betting option, the at least one prize money value corresponding to the at least one optional betting option that has been betted may be activated, such that the player has an opportunity to obtain the at least one prize money value that has been activated. Therefore, the game system of the present invention can induce the player to bet on the optional betting option by virtue of the presence and display of the prize money values, as well as the player's desire to obtain the prize money values, thereby increasing the willingness of the player to raise bets and the revenue of the game system.

  • Publication number: 20200105103
    Abstract: The present invention mainly includes a score determination unit determining whether a game score of a player satisfies a score threshold value and accordingly generating a score determination signal. A processing unit determines whether to enable an additional bet option according to the score determination signal, and then the processing unit controls a game status display unit to display an enabled status of the additional bet option. When the additional bet option is in the enabled status, the player selects to bet to generate an additional bet signal, and the processing unit controls an odds generation unit to generate at least one of additional random odds. Therefore, the player obtains payouts of the additional random odds.
