14 results about "Major histocompatibility complex" patented technology

The major histocompatibility complex (MHC) is a set of genes that code for cell surface proteins essential for the acquired immune system to recognize foreign molecules in vertebrates, which in turn determines histocompatibility. The main function of MHC molecules is to bind to antigens derived from pathogens and display them on the cell surface for recognition by the appropriate T-cells. MHC molecules mediate interactions of leukocytes, also called white blood cells (WBCs), which are immune cells, with other leukocytes or with body cells. The MHC determines compatibility of donors for organ transplant, as well as one's susceptibility to an autoimmune disease via crossreacting immunization. The human MHC is also called the HLA (human leukocyte antigen) complex (often just the HLA). The MHC in mice is called the Histocompatibility system 2 or just the H-2.

Peptide search system for immunotherapy

ActiveUS12651647B2BiostatisticsNeural learning methodsBinding peptidePeptide vaccine
A system for binding peptide search for immunotherapy is presented. The system includes employing a deep neural network to predict a peptide presentation given Major Histocompatibility Complex allele sequences and peptide sequences, training a Variational Autoencoder (VAE) to reconstruct peptides by converting the peptide sequences into continuous embedding vectors, running a Monte Carlo Tree Search to generate a first set of positive peptide vaccine candidates, running a Bayesian Optimization search with the trained VAE and a Backpropagation search with the trained VAE to generate a second set of positive peptide vaccine candidates, using a sampling from a Position Weight Matrix (sPWM) to generate a third set of positive peptide vaccine candidates, screening and merging the first, second, and third sets of positive peptide vaccine candidates, and outputting qualified peptides for immunotherapy from the screened and merged sets of positive peptide vaccine candidates to support downstream clinical decision making.

Method and assay device for predicting t cell activation of peptide-mhc

ActiveCN117121109BActivation cellsT cell
This method for predicting T cell activation via peptide-MHC includes the following steps: wherein the analytical device: receives genetic data from a patient; identifies, based on the genetic data, the first amino acid sequence of the major histocompatibility complex (MHC) and the second amino acid sequence of an antigen produced by tumor cells; generates a matrix indicating the interrelationship between the first and second amino acid sequences in units of individual amino acids; and inputs the matrix into a trained neural network model to determine whether T cells secrete at least a threshold amount of cytokines due to the binding of MHC to the antigen.
