Follicular helper T cells, or Tfh cells, have a crucial role in immune defense. Without Tfh cells, B cells cannot form germinal center, or GC, responses during which high-affinity antibodies are generated.
Some PD-1+CXCR5+CD4+ T cells will become germinal center-Tfh cells that are essential for B cells to become high-affinity antibody-producing cells. Others do not take that path, instead becoming memory T cells. Fangming.

Tumor-stromal interactions within the tumor microenvironment (TME) influence lung cancer progression and response to therapeutic interventions, yet traditional
in vitro studies fail to replicate the complexity of these interactions. Herein, we developed three-dimensional (3D) lung tumor models that mimic the human TME and demonstrate tumor-stromal crosstalk mediated by extracellular vesicles (EVs). EVs released by tumor cells, independent of p53 status, and fibroblasts within the TME mediate
Study: Individuals recovering from COVID-19 helpful for Sustained cellular immune dysregulation ANI | Updated: Jan 03, 2021 22:10 IST
Birmingham [UK], January 3 (ANI): A recent study has determined that Covid-19 patients might be helpful for clinicians to better understand how the unknown SARS-CoV-2 virus acts.
According to a study published in the Journal of Clinical Investigation, many infected patients remain asymptomatic or have mild symptoms. Others, especially those with comorbidities, can develop severe clinical disease with atypical pneumonia and multiple system organ failures.
Since the first cases were reported in December 2019, the SARS-CoV-2 virus that causes COVID-19 has surged into a pandemic, with cases and deaths still mounting. Ongoing observational clinical research has become a priority to better understand how this previously unknown virus acts, and findings from this research can better inform treatment and vaccine desig
