Humoral Immunostimulation
Interaction of microgram quantities of highly purified rabbit anti-TNP antibodies with TNP-substituted HeLa, HEp-2, and L cells caused an intense stimulation of radioactive nucleoside ([(125)I]UdR and [(3)H]TdR) uptake which was maximal 24-72 h after exposure of cells to antibody. The stimulation of nucleoside uptake and presumaly DNA synthesis was shown to be immuno logically mediated because ...
متن کاملHumoral immunostimulation. IV. Role of complement
When L cells were treated with anti-L-cell antibody in medium containing heat-inactivated fetal calf serum, nucleoside uptake and cell growth were stimulated. The response was markedly increased when fresh, unheated sera from calves, guinea pigs, humans, mice, or rabbits were also present. The factors in unheated serum responsible for the enhancement of immunostimulation were studied. Using low...
متن کاملHumoral immunostimulation. V. Selection of variant cell lines
A permanent L-cell variant cell line (LC1) was isolated by the growth of the parent L-cell line (L) in the presence of a cytostimulatory dose (1:200) of rabbit anti-L-cell antiserum (AL) for 9 mo. LC1 differed from L in many aspects: (a) it was larger (1,533 mm3 vs. 1,284 mm3), (b) it grew faster (1.5- to 2-fold), (c) it grew in aggregated fashion, (d) its growth was no longer stimulated by AL,...

متن کاملImmunostimulation: The Sense in Antisense Technology
The post-human genomic era has led to the development of therapies, which specifically target molecular pathways responsible for diseases. The original concept of antisense therapy was to simply turn off gene's activity by a short synthetic DNA sequence, having sequence complementary to mRNA and thus block the production of undesirable protein. However, during the last two decades this concept ...
