Lymphoblast. A lymphoblast is a modified naive lymphocyte with altered cell morphology. It occurs when the lymphocyte is activated by an antigen and increased in volume by nucleus and cytoplasm growth as well as new mRNA and protein synthesis.
LL-100 panel cell lines cover the full spectrum of human leukemia and lymphoma including T-cell, B-cell and myeloid malignancies. [ 1 ] List of LL-100 cell lines
Lymphoblastoid cell lines established from blood samples of humans who were centenarians (100 years old or older) have significantly higher PARP activity than cell lines from younger (20 to 70 years old) individuals, [13] again indicating a linkage between longevity and repair capability.
The Human Cell Atlas project, which started in 2016, had as one of its goals to "catalog all cell types (for example, immune cells or brain cells) and sub-types in the human body". [13] By 2018, the Human Cell Atlas description based the project on the assumption that "our characterization of the hundreds of types and subtypes of cells in the ...
The life span of 13 mammalian species correlated with poly(ADP ribosyl)ation capability measured in mononuclear cells. Furthermore, lymphoblastoid cell lines from peripheral blood lymphocytes of humans over age 100 had a significantly higher poly(ADP-ribosyl)ation capability than control cell lines from younger individuals.
The JY cell line is an Epstein–Barr virus (EBV)-immortalised B cell lymphoblastoid line. JY cells express HLA class-I A2 and class-II DR. JY is a suspension cell line, although the cells are known to grow in clumps. The growth medium is RPMI 1640, 10% fetal calf serum and 1% L-glutamine. [1] JY cells are positive for murine leukemia virus. [2]
Interleukin 12 (IL-12) is an interleukin that is naturally produced by dendritic cells, [1] macrophages, neutrophils, helper T cells and human B-lymphoblastoid cells in response to antigenic stimulation. IL-12 belongs to the family of interleukin-12.
HeLa (/ ˈ h iː l ɑː /) is an immortalized cell line used in scientific research. It is the oldest human cell line and one of the most commonly used. [1] [2] HeLa cells are durable and prolific, allowing for extensive applications in scientific study.
