This video demonstrates the process of transducing human neuronal cells with a lentivirus encoding a mutant human tau protein tagged with yellow fluorescent protein (YFP) to study protein aggregation. It outlines the steps from viral entry to mutant tau expression, culminating in the formation of visible cytoplasmic tau aggregates in the neurons.

The Nucleosome Core Particle

Nucleosomes are the DNA-histone complex, where the DNA strand is wound around the histone core. The histone core is an octamer containing two copies of H2A, H2B, H3, and H4 histone proteins. The paradox Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...

We have developed a lentiviral vector that possesses, in addition to the Tat-responsive LTR, the Rev-response element (RRE) that can regulate reporter gene expression in an HIV-1 Tat- and Rev-dependent fashion. The vector permits the specific detection of replicating HIV in living cells via the expression of GFP.

In this video, we demonstrate the laser-assisted permeation of the protective layer of zona pellucida in mouse fertilized eggs for facilitating lentiviral gene delivery. Lentivirus enables the generation of transgenic animals with a gene of interest stably integrated into their genome.
FAQs
Processing of the Gag polyprotein converts a precursor into coordinated structural components during viral maturation. This cleavage produces matrix, capsid, nucleocapsid, and related proteins with different roles in particle organization, genome protection, and RNA packaging. The timing and completeness of this transition therefore affect whether newly formed particles acquire the architecture needed for subsequent infection.
These components should be analyzed as a coordinated set rather than interchangeable parts. Capsid supplies the protective shell, whereas nucleocapsid binds viral RNA and helps package it into new particles. Matrix and related cleavage products contribute to the broader structural organization produced from Gag. This distinction lets researchers relate architecture, genome handling, and maturation to separate functions.
Core-protein function extends beyond particle construction. During infection, coordinated disassembly of the incoming core and interactions with host-cell factors influence reverse transcription and intracellular trafficking. These events connect the physical state of the core with infection progress: a particle must be assembled and protected initially, yet undergo appropriate remodeling during infection for productive infection to proceed.
A focused study can follow the proteins across several linked stages: production from Gag, cleavage during maturation, participation in particle formation, RNA association, and behavior during disassembly. Researchers can then relate those observations to reverse transcription, intracellular trafficking, and productive infection. This sequence connects molecular events with infection-related outcomes without treating each protein in isolation.
Because core proteins participate in particle formation, genome protection, RNA packaging, disassembly, and infection-related processes, they provide several points for investigating antiviral intervention. Comparing how changes in these functions affect maturation or productive infection can identify vulnerable stages of the viral life cycle. Lentiviral core proteins are therefore relevant to research on potential antiviral drug targets.
Vector development must account for the structural and infection-related functions supplied by lentiviral core proteins. Their contributions to particle formation, genome protection, RNA packaging, disassembly, trafficking, and productive infection can influence how a vector is designed or optimized. Studying these components helps connect vector properties with the underlying biology of lentiviral replication and gene delivery.
