On the other hand, CEACAM1 expression modulates melanoma cell escape from immunologic attacks; when melanoma cells and tumor-infiltrating lymphocytes
are coincubated in vitro, surviving melanoma cells increase CEACAM1 expression, which is dependent on constant presence of interferon gamma.
In this study, we showed that the presence of large numbers of tumor-infiltrating lymphocytes
was inversely correlated with the incidence of nodal metastasis in our cohort of patients with oropharyngeal squamous cell carcinoma, particularly those who were HPV-positive.
59) We have also used IA in an on-slide "flow cytometry"-type approach to quantitate inflammatory cells in autoimmune pancreatitis, (39) and it is possible that such methods may become important in quantitating inflammatory cells in a variety of applications (eg, tumor-infiltrating lymphocytes
in gastrointestinal tract cancers).
Prior research had shown that human melanoma tumors often contain mutation-reactive immune cells called tumor-infiltrating lymphocytes
In situ cytokine production by breast cancer tumor-infiltrating lymphocytes
Several weeks ago, the researchers removed white blood cells called tumor-infiltrating lymphocytes
from each patient's tumors.
NEW HISTOPATHOLOGIC THERANOSTIC MARKERS: TUMOR-INFILTRATING LYMPHOCYTES
The company's lead product candidate, LN-144, is reportedly an adoptive cell therapy using tumor-infiltrating lymphocytes
(TIL) for the treatment of patients with refractory metastatic melanoma, and is based on a clinical Cooperative Research and Development Agreement with the National Cancer Institute.
CD20+ tumor-infiltrating lymphocytes
have an atypical CD27-memory phenotype and together with CD8+ T cells promote favorable prognosis in ovarian cancer.
These cells, called tumor-infiltrating lymphocytes
(TIL), home in on and destroy tumors.
The company stated that the license is based on two provisional patent applications, filed under 'Compositions and Methods for Improving Tumor-Infiltrating Lymphocytes
for Adoptive Cell Therapy.
The hope is that the secretion of cytokines would stimulate a tumor-specific immune response resulting in tumor destruction at other sites or would allow the collection of tumor-infiltrating lymphocytes
from adjacent lymphoid tissue.
