AI Article Synopsis

  • The study examined the effectiveness of oral polio vaccines in Saudi Arabia by testing children’s antibodies post-vaccination.
  • Approximately 209 vaccinated children were analyzed, with blood samples collected at nine months to measure their immune response.
  • The results showed varying success rates: 79% for Type 1, 88% for Type 2, and 65% for Type 3, indicating a need for a new vaccination strategy.

Article Abstract

This is a national seroprevalence study conducted in Saudi Arabai in 1991G to determine postvaccination poliovirus antibody. Two hundred and nine children vaccinated with three oral polio vaccines at three, four, and five months of age were included in the study representing the five main regions in Saudi Arabia. Blood samples were collected at the age of nine months. Cytopathic effect (CPE) neutralization was used to determine the level of polio antibody. A dilution of 1/8th or more was defined as positive. Seventy-nine percent, 88% and 65% of the children were positive for Type 1, Type 2, and Type 3, respetively. Development of a new strategy of polio vaccination is needed.

Article Synopsis
  • The serotype 2 oral poliovirus vaccine (OPV2) can revert and lead to vaccine-derived poliovirus, posing a threat to eradication efforts, especially in immunocompromised individuals.
  • A study analyzed changes in specific amino acids within the virus's structure that affect its ability to be neutralized by immune serum from vaccinated individuals.
  • The findings indicate that mutations in the virus significantly reduce the effectiveness of antibodies, highlighting the need for ongoing monitoring of immunocompromised populations and maintaining high vaccination rates in these communities.

Targeting the immune privilege of tumor-initiating cells to enhance cancer immunotherapy.

Tumor-initiating cells (TICs) possess the ability to evade anti-tumor immunity, potentially explaining many failures of cancer immunotherapy. Here, we identify CD49f as a prominent marker for discerning TICs in hepatocellular carcinoma (HCC), outperforming other commonly used TIC markers. CD49f-high TICs specifically recruit tumor-promoting neutrophils via the CXCL2-CXCR2 axis and create an immunosuppressive milieu in the tumor microenvironment (TME).

Enteroviruses (EV) initiate replication by binding to their cellular receptors, leading to the uncoating and release of the viral genome into the cytosol of the host cell. Neutralising antibodies (NAbs) binding to epitopes on enteroviral capsid proteins can inhibit this infectious process through several mechanisms of neutralisation in vitro. Fc-mediated antibody effector functions such as antibody-dependent cell-mediated cytotoxicity and antibody-dependent cellular phagocytosis have also been described for some EV.

R. China; Laboratory of Data Discovery for Health Limited (D(2)4H), Hong Kong Science Park, Hong Kong Special Administrative Region, P. R. China; The University of Hong Kong-Shenzhen Hospital, Shenzhen, P. R. China.

Objectives: This study aimed to assess the long-term persistence of neutralizing antibodies (nAb) titres and seroprotection proportions after the fourth and fifth doses of inactivated polio vaccine (IPV).

Methods: Serum samples from 299 children in Hong Kong were collected and used to estimate the persistence of nAb titres and seroprotection proportions by neutralisation test.

Results: The mean nAb titres against poliovirus types 1, 2, and 3 (PV1, PV2, and PV3) 1 month after receiving the fourth dose of IPV at 19 months of age were 2068 (95% credible interval, 1517-2864); 4705 (3439-6436); and 2758 (1894-4086); respectively, but declined substantially in 4 years to 268 (222-325), 751 (630-900), and 411 (323-521), respectively.

Protective role of antibodies in enteric virus infections: Lessons from primary and secondary immune deficiencies.

Immunol Rev

Article Synopsis
  • - Enteric viruses are a leading cause of acute gastroenteritis globally, particularly affecting children and the elderly, and can also lead to severe neurological diseases like poliomyelitis.
  • - Understanding of immune responses to these viruses is primarily derived from animal studies, although vaccines (like those for poliovirus and rotavirus) have advanced our knowledge, particularly regarding protective immunity.
  • - Research on Inborn Errors of Immunity highlights the importance of antibodies, showing that individuals with inadequate antibody production are more susceptible to prolonged enteric viral infections and related neurological issues due to the role of B cells and immunoglobulins in viral control.
