Why are lentiviruses safer?

Why are lentiviruses safer?

Lentivirus is regarded as a biosafety level 2 material and safe to use due to its modified features (deletion of a number of accessory virulence genes , minimal genome of the viral particles, non-replicating and self-inactivation features), making it incapable of producing virus once infected into the host cell.

Why is it called lentivirus?

Lentiviruses are grouped in a genus within the family Retroviridae. The name derives from the Latin word lenti which means slow, alluding to the long incubation period of the disease, which in most cases lasts years.

How do you make lentiviruses?

Reagent Preparation

  1. Dissolve 0.129 g of chloroquine diphosphate salt in 10 mL of sterile water.
  2. Filter sterilize through a 0.22 μm filter.
  3. Aliquot 50-100 μL and store at -20 ℃.
  4. Aliquots can be thawed and stored at 4 ℃ prior to use. Thawed aliquots should be discarded after 1-2 months.

How do lentiviruses integrate?

Where does lentivirus integrate? Genome-wide studies of viral integration have shown that lentiviruses most often integrate into actively transcribed genes, and that this preference is conserved across target species.

What risk group is lentivirus?


Agent Type Risk Group Biosafety Level
Viral Vector RG-3 BSL-2

How many lentiviruses are there?

According to the recent classification of International Committee on Taxonomy of Viruses (ICTV), Lentivirus genus belongs to the family Retroviridae and currently comprises of nine species: seven animal lentiviruses and two human lentiviruses.

Can lentivirus infect humans?

Acute infection with human lentiviruses can appear as non-specific “flu-like” and “mononucleosislike” symptoms, including myalgia, arthralgia, diarrhea, nausea, vomiting, headache, hepatosplenomegaly, weight loss and neurological symptoms.

Where do lentiviruses integrate?

Lentiviral vectors are fundamentally integrated into the host genome, but their integration sites are generally unpredictable, which may increase the uncertainty for their use in therapeutics. To determine the viral integration sites in the host genome, several PCR-based methods have been developed.
