Therapeutic HIV Peptide Vaccine
No full textTherapeutic vaccines aim to control chronic HIV infection and eliminate the need for lifelong antiretroviral therapy (ART). Therapeutic HIV vaccine is being pursued as part of a functional cure for HIV/AIDS. We have outlined a basic protocol for inducing new T cell immunity during chronic HIV-1 infection directed to subdominant conserved HIV-1 epitopes restricted to frequent HLA supertypes. The rationale for selecting HIV peptides and adjuvants are provided. Peptide subunit vaccines are regarded as safe due to the simplicity, quality, purity, and low toxicity. The caveat is reduced immunogenicity and hence adjuvants are included to enhance and direct the immune response. Although the vaccine has been tested in ART naïve individuals, we recommend future testing of the vaccine during (early started) ART that improves immune function and to select individuals likely to benefit. Peptides representing other epitopes may be used.</p
Rapid bedside inactivation of Ebola virus for safe nucleic acid tests
No full textRapid bedside inactivation of Ebola virus would be a solution for the safety of medical and technical staff, risk containment, sample transport and high-throughput or rapid diagnostic testing during an outbreak. We show that the commercially available MagNA Pure lysis/binding buffer used for nucleic acid extraction inactivates Ebola virus. A rapid bedside inactivation method for nucleic acid tests is obtained by simply adding MagNA Pure lysis/binding buffer directly into vacuum blood collection EDTA-tubes using a thin needle and syringe prior to sampling. The ready-to-use inactivation vacuum tubes are stable for more than 4 months and Ebola virus RNA is preserved in the MagNA Pure lysis/binding buffer for at least 5 weeks independent of the storage temperature. We also show that Ebola virus RNA can be manually extracted from MagNA Pure lysis/binding buffer-inactivated samples using the QIAamp Viral RNA mini kit. We present an easy and convenient method for bedside inactivation using available blood collection vacuum tubes and reagents. We propose to use this simple method for fast, safe and easy bedside inactivation of Ebola virus for safe transport and routine nucleic acid detection
Protective properties of a human IgG preparation rich in antibodies to a wide spectrum of lipopolysaccharides
No full textZika virus epidemic
No full textZika virus is endemic in several parts of the world. February 1, 2016 Zika virus was declared a public health emergency by the WHO. This declaration is mainly due to a convincing association between Zika virus infection during pregnancy and birth defects, like microcephaly, among some of the newborns. Imported cases of Zika virus infection to North America, Europe and Denmark have been described. The infection in itself is mild and self-limiting. The available diagnostic methods are under development, validation and evaluation. In Denmark, some promising diagnostics are available at Statens Serum Institut.</p
