Low on Antibodies, Blood Cancer Patients Can Fight off COVID-19 with T Cells
Antibodies aren’t the only immune cells needed to fight off COVID-19 — T cells are equally important and can step up to do the job when antibodies are depleted, suggests a new Penn Medicine study of blood cancer patients with COVID-19 published in Nature Medicine.
COVID-19 mRNA Vaccines are Immunogenic in Pregnant and Lactating Women, Including Against Viral Variants
In a new study from Beth Israel Deaconess Medical Center researchers evaluated the immunogenicity of COVID-19 mRNA vaccines in pregnant and lactating women who received either the Pfizer or Moderna COVID-19 vaccines. They found that both vaccines triggered immune responses in pregnant and lactating women.
Chula Innovations for Society to Fight COVID-19
Chulalongkorn University has taken a bold step in commutating its transformation to an innovation-centric university with its “Innovations for Society” campaign. The campaign uses a short movie to inform the public about the various innovations that Chula has successfully developed to fight the COVID-19 pandemic, as part of Chula’s mission to play a leading role in “Creating Knowledge and Innovation to Promote Sustainable Development for Society”.
2021 Warren Alpert Prize Awarded to Two Scientists for RNA Discoveries
The 2021 Warren Alpert Foundation Prize has been awarded to scientists Lynne Maquat and Joan Steitz for seminal discoveries in the biology and function of RNA, the workhorse molecule of cells. Their discoveries have reshaped the understanding of RNA’s myriad roles in healthy cell function and in disease-causing dysfunction and have informed the conceptualization and design of RNA-based therapies in various stages of development.
