Humoral Immunostimulation
نویسندگان
چکیده
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 unsubstituted cells were not stimulated by anti-TNP antibody, normal rabbit gamma globulin did not stimulate TNP-cells, and a hapten inhibitor, epsilon-DNP-lysine, prevented the stimulation of TNP-cells by anti-TNP antibody. These findings demonstrate that interaction of antibody with cell surface antigen can alter cell membrane transport, and possibly can enhance cell growth.

HUMORAL IMMUNOSTIMULATION I. INCREASED UPTAKE OF [I~SI]IoDODEOXYLrRIDINE AND [3H]THr~mINE INTO TNP-CELLS TREATED WITH ANTI-TNP ANTIBODY* BY WILLIAM T. SHEARER,$
Evidence to support an irnmunostimulafion theory of tumor growth has recently been reviewed by Prehn (1, 2). Basically the immunostimulation theory proposes that both humoral and cellular immune responses can, under certain conditions, facilitate tumor growth by direct effect upon the tumor cells. Enhancement of tumor cell growth, on the other hand, is thought to be due to an enhancing antibody...
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 کاملCpG-ODN Class C Mediated Immunostimulation in Rabbit Model of Trypanosoma evansi Infection
CpG oligodeoxynucleotides (CpG-ODN) stimulate immune cells from a wide spectrum of mammalian species. Class C CpG-ODN is relatively stable and has the combined immune effects of both A and B classes of CpG-ODN. Trypanosoma evansi produces the state of immuno-suppression in the infected hosts. The current chemotherapeutic agents against this parasite are limited in number and usually associated ...
متن کاملImmunostimulants: Towards Temporary Prevention of Diseases in Marine Fish
Due over the last years, marine aquaculture has grown into a very significant industry in many parts of the world, and in most developed countries marine fish are farmed intensively under conditions of high population density, infectious diseases pose a constant and highly cost threat to successful animal husbandry. Antibiotics provide a useful means of helping to control many bacterial disease...
متن کاملThe Influence of Bovine Thymic Extract on the Immune Response in Irradiated Wistar Rats
Immunomodulation is a phenomenon that is based on the influence of different endogenous and exogenous substances on the function of molecules and cells pertaining to the immune system. Some components extracted from the bovine thymus have immunomodulating features and can, both in animals and humans, by suppressing the immune response (humoral and/or cellular) bring about immunostimulation and ...
متن کاملImmunostimulation in the urinary bladder by local application of Nocardia rubra cell-wall skeletons (Rubratin) and bacillus Calmette-Guérin as therapy for superficial bladder cancer: a comparative study.
Twelve patients with superficial bladder cancer were treated with intravesical instillations of Rubratin (ASTA Pharma AG, Frankfurt, Germany), a cell-wall preparation of Nocardia rubra. The objective was to compare the immunostimulating effect of Rubratin with that of bacillus Calmette-Guérin (BCG). Local immunostimulation was determined by cytokine induction in serially collected urine samples...
