CAL20 C SARS-CoV-2 variant skyrocketing in California evades host immune response

CAL20.C SARS-CoV-2 variant skyrocketing in California evades host immune response The effect of different neutralizing antibodies, both vaccine-elicited and from convalescent sera, suggests new variants are emerging that can evade the human immune response. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) binds to host cells via its spike protein, which has two parts, the S1 and S2 subunits. The S1 subunit has the receptor-binding domain (RBD) and the N-terminal domain (NTD). The RBD binds to the host angiotensin-converting enzyme 2 (ACE2) to infect host cells. Neutralizing antibodies are produced against both the RBD and NTD by infected and vaccinated individuals. Some RBD-specific monoclonal antibodies are currently under clinical trials or approved for use to treat COVID-19 patients.

As her ninth year post-successful colorectal cancer surgery approaches, Terrell Cleare, 50, still thinks about being diagnosed with stage three colorectal cancer and what she went through to save her life. Today, she expresses gratitude daily, but admits March, which is recognized as colorectal cancer awareness month, is special to her and reminds her that she can be an inspiration to others. “I can tell my story. I’m living proof that this is survivable,” said Cleare who was diagnosed with stage three colorectal cancer at age 42. “Every day of my life I thank God that I’ve come this far and to be cancer-free.
