Description |
LIGHT is a member of the TNF superfamily and can function as a costimulatory molecule for human naive T cells to proliferate. It can be a potential gene adjuvant. |

Components |
LIGHT, a member of TNF superfamily, can function as a costimulatory molecule for human na?ve T cells to proliferate and can be a potential gene adjuvant. |
|
Structure |
Eukaryotic expression plasmid pcDNA-nef was constructed by inserting a full-length nef gene into pcDNA3.1(+). LIGHT expression plasmids were also used. |
|
Preparation |
The eukaryotic expression plasmid pcDNA-nef was constructed by inserting a full-length nef gene into pcDNA3.1(+). |
|
Dosage |
BALB/c mice were immunized with HIV-1 nef DNA vaccine plasmids alone or in combination with LIGHT expression plasmids, but specific dosage amounts are not provided. |
|
Function |
In this study, the eukaryotic expression plasmid pcDNA-nef was constructed by inserting the full-length nef gene into pcDNA3.1(+), and in vitro transfection confirmed successful nef expression in mammalian cells. BALB/c mice immunized with HIV-1 nef DNA vaccine plasmids, alone or combined with LIGHT expression plasmids, were evaluated for humoral and cellular immune responses. While the nef DNA vaccine induced anti-Nef antibodies, lymphocyte proliferation, and CTL activity, co-immunization with LIGHT plasmids significantly enhanced these responses. These results demonstrate that the nef-expressing vector elicits specific immunity against HIV-1 Nef, and LIGHT acts as a potent gene adjuvant for HIV-1 DNA vaccination. |
