TIL Therapy for Melanoma: Targeting MAAs and Neoantigens
Tumor-infiltrating lymphocytes (TILs) are immune cells that migrate into the tumor microenvironment and recognize two main antigen classes: melanoma-associated antigens (MAAs) and patient-specific neoantigens. This article explains the mechanisms, key antigens like PRAME and MART-1, strategies to enrich potent TIL populations, and the translational outlook in melanoma immunotherapy.
Peptide Mass Calculator: Molecular Mass and Key Properties for Research
A peptide mass calculator helps researchers determine molecular mass, sum formula, XlogP, TPSA, Van-der-Waals volume, and counterion counts for peptide sequences. This article explains these properties, how the calculator works, and the difference between molecular mass and molar mass for accurate lab work.
What Makes a Research Peptide 'High Purity'? Standards Explained
Breaking down what 'high purity' actually means for research peptides — the analytical standards, testing methods, and quality benchmarks that distinguish research-grade from crude material.
MHC Class I vs II Peptide Binding: T Cell Presentation Explained
Adaptive immunity relies on T cell recognition of peptide-MHC complexes. MHC class I binds short endogenous peptides (8-10 amino acids) in a closed groove, presenting to CD8+ cytotoxic T cells. MHC class II binds longer exogenous peptides (13-25 amino acids) in an open groove, presenting to CD4+ helper T cells. Understanding these structural and functional differences is key for designing peptide-based vaccines and T cell assays.
Epstein-Barr Virus: Biology, Entry, and Early Infection Mechanisms
Epstein-Barr virus (EBV), first identified in 1964 in Burkitt's lymphoma, is a human herpesvirus that establishes lifelong persistence in memory B cells. This article covers EBV's virion structure, cell entry pathways into epithelial cells and B lymphocytes, and the pre-latent phase where viral gene expression begins to reprogram host cells for survival.
