Does decrease of CD44-positive cells correlate with tumor response to chemotherapy in patients with gastrointestinal cancer?
We were able to monitor changes of CD44 expression after chemotherapy and detected a correlation between the CD44 decrease and the patients' response to treatment. Our findings show that CD44 detection helps to monitor chemotherapy response in patients with gastrointestinal cancer.
Our results suggest that antibody responses against the C-terminal region of HIV gp120 and HLA class I may represent markers of apparent natural protection against HIV-1 infection.
