Advances in immunotherapy for glioblastoma multiforme.

Glioblastoma multiforme (GBM) is the most common and aggressive malignant brain tumor of the central nervous system and has a very poor prognosis. The current standard of care for patients with GBM involves surgical resection, radiotherapy, and chemotherapy. Unfortunately, conventional therapies have not resulted in significant improvements in the survival outcomes of patients with GBM; therefore, the overall mortality rate remains high.

Assessing the Knowledge and Attitude toward COVID-19 Vaccination in Saudi Arabia.

COVID-19 was declared a pandemic by the WHO in March 2020. The most promising strategy to control the pandemic was to develop a vaccine. However, vaccination hesitancy is a major threat to world public health.

Prolonged humoral and cellular immunity in COVID-19-recovered patients.

By the beginning of 2021, the battle against coronavirus disease 2019 (COVID-19) remains ongoing. Investigating the adaptive immune response against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19, in patients who have recovered from this disease could contribute to our understanding of the natural host immune response. We enrolled 38 participants in this study.

Disruption of Serinc1, which facilitates serine-derived lipid synthesis, fails to alter macrophage function, lymphocyte proliferation or autoimmune disease susceptibility.

During immune cell activation, serine-derived lipids such as phosphatidylserine and sphingolipids contribute to the formation of protein signaling complexes within the plasma membrane. Altering lipid composition in the cell membrane can subsequently affect immune cell function and the development of autoimmune disease. Serine incorporator 1 (SERINC1) is a putative carrier protein that facilitates synthesis of serine-derived lipids.

Sleeping Beauty Transposon Mutagenesis as a Tool for Gene Discovery in the NOD Mouse Model of Type 1 Diabetes.

A number of different strategies have been used to identify genes for which genetic variation contributes to type 1 diabetes (T1D) pathogenesis. Genetic studies in humans have identified >40 loci that affect the risk for developing T1D, but the underlying causative alleles are often difficult to pinpoint or have subtle biological effects. A complementary strategy to identifying "natural" alleles in the human population is to engineer "artificial" alleles within inbred mouse strains and determine their effect on T1D incidence.
