Using viral vectors against a lethal flu virus

influenza treatmentA novel treatment against lethal influenza infection was tested in mice.

  • A viral vector was created that contained genes for antibodies against influenza virus hemagglutinin;
  • Viral vectors were given to mice through hydrodynamic injection;
  • Vectors led to the expression of neutralizing antibodies both in serum and mucosal tissues of mice;
  • A single injection was sufficient to protect mice against lethal flu infection.

The study shows that passive immune therapy should be tested for influenza treatment in humans.

Antibodies against HIV found

hivThe efficacy of broadly neutralizing monoclonal antibodies against human immunodeficiency viruses (HIV) infection was evaluated during a pre-clinical study in humans.

  • Antibodies were tested in healthy humans and HIV-infected patients;
  • The antibodies lead to a decrease in viral load;
  • For patients that interrupted antiretroviral therapy, the rebound of the infection was delayed;
  • Strains resistant to antibodies have emerged, so their potential is limited;

Though HIV viruses can develop resistance to antibodies used, there is a room for improvement in this type of treatment through various manipulation approaches.

Proteomic help understand antiviral immunity

antigensAntiviral immunity is a complex process involving both branches of the adaptive immune system. Proteomics allows gaining new insights into this process.

  • Proteomics allows finding new viral antigens;
  • Proteomics methods allow the scientist to track the presentation of antigens to T and B cells;

In short, proteomics allows finding new vaccine candidates and helps in the treatment and monitoring of viral infections.

A new role for NKT cells

zika virusIt was found that Natural Killer T (NKT) cells are crucial for mounting an antiviral immune response.

  • NKT is critical for the induction of B cells in response to viral infections.
  • NKT cells produce around 70% of IL-4 at the early stage of infection;
  • Increase in NKT cells activity and IL-4 production correlates with an increase in neutralizing antibodies in macaques infected with Zika virus.

It was concluded that NKT cells are an essential branch that links innate immunity with adaptive immune response in viral infections.

Nanoparticles against cancer

cancer ribbonA novel application of nanoparticles in cancer therapy was proposed.

  • Nanoparticles can safely encapsulate other molecules and serve as drug delivery systems;
  • Their surfaces can contain antibodies that will enable targeted delivery to specific cell types;
  • Nanoparticles can deliver antigens directly to T-cells, priming them against cancer cells;
  • They can also be used to boost the immune reaction against cancer by delivering cytokine cocktails.

Nanoparticles have vast potential in cancer treatment and may become a cheaper, safer and more effective treatment option.

The new HPV vaccine prevents infections in young men

hpv vaccineA long-term study of the efficacy of newly developed quadrivalent HPV vaccine in young men was undertaken.

  • Young men between 16-26 years old were given 3 doses of HPV vaccine;
  • 917 participants in total were followed for approximately 11 ½ years;
  • The men were evaluated for the presence of genital lesions or anal cancer post vaccination.
  • No new cases of lesions, neoplasias or anal cancers were reported in the studied population.

The HPV vaccine provides durable protection and mitigates the risk of anal cancer development.

Thymosin alpha 1 as an important biomarker

serum bandageThymosin alpha 1 (Ta1) levels in the serum were evaluated in some different conditions.

  • Ta1 is an indicator of immune dysregulation;
  • An increase in Ta1 levels is observed in hepatitis B, multiple sclerosis and sepsis;
  • Cystic fibrosis is associated with lower levels of Ta1;

The variability of Ta1 levels can be an indicator of the patient’s condition and also can be used for proper treatment prescription.

Peptide vaccines may be safer than traditional ones

peptide vaccineConventional vaccines against viral infections contain components that are immunogenic but can cause autoimmune reactions. It was proposed to use peptide vaccines instead.

  • Using peptide vaccines means avoiding adjuvants that can potentially trigger inflammatory responses;
  • Peptide vaccines do not get contaminated with non-viral proteins of cellular origin;
  • Potential vaccine candidates can be selected both from capside proteins or non-structural viral peptides;
  • The vaccines should activate both CD4 and cytotoxic CD8 T cells.

Peptide vaccines may be easier to manufacture using modern methods and would be safer to use in the long run.
