[Construction and identification of mouse BTLA lentiviral expression vector]

Area of Science:

• Molecular Biology
• Immunology
• Gene Therapy

Context:

• Mouse B and T lymphocyte attenuator (mBTLA) plays a crucial role in immune regulation.
• Developing efficient gene delivery systems is essential for studying immune cell function.
• Lentiviral vectors are widely used for stable gene transfer in mammalian cells.

Purpose:

• To construct and identify a lentiviral vector capable of expressing mBTLA.
• To validate the efficacy of the constructed vector in delivering and expressing the mBTLA gene.

Summary:

• The coding sequence of mBTLA was amplified and cloned into a lentiviral transfer vector.
• Lentiviral particles were packaged using 293T cells and liposomes.
• Successful construction and packaging were confirmed by sequencing, PCR, and titer assays (1.3×10^8 pfu/mL).
• RT-PCR and Western blotting confirmed effective expression of mBTLA mRNA and protein.

Impact:

• Provides a reliable tool for investigating mBTLA function in immunological studies.
• Facilitates research into immune modulation and potential therapeutic applications.
• Enables further exploration of lymphocyte attenuation mechanisms.
