Relative sensitivity of fetal and newborn mice to induction of hapten- specific B cell tolerance
Mice were rendered tolerant to the hapten fluorescein (FLU) by a single injection of FLU-human gamma globulin (FLU5HGG) 2-3 d after birth or via the maternal circulation at 14.5 d of fetal life. After 7-9 d, the degree of functional nonresponsiveness induced in vivo among splenic FLU-specific B cells of tolerized mice was assessed by limiting-dilution analysis in vitro, and the serum levels of ...
متن کاملT and B cell in hapten-specific carrier-determined tolerance
BDF1 mice were made tolerant by a single i.v. injection of 1 mg of DNAP-gamma1 or by weekly i.v. injections of 0.2 mg of DNP-gamma1 given for a month. In both instances, spleen cells of tolerant animals were fractionated to obtain pure populations of T cells (nonimmunoglobulin-bearing cells), referred to as tolerant T cells, and B cells (immunoglobulin-bearing cells) referred to as tolerant B c...
متن کاملInduction of hapten-specific tolerance by interleukin 10 in vivo
Interleukin 10 (IL-10) is released during the induction phase of contact sensitivity and was shown in prior functional studies to convert epidermal Langerhans cells (LC) from potent inducers of primary immune responses to specifically tolerizing cells in vitro. To investigate whether IL-10 also subserves the function of a tolerizing agent in vivo ears of BALB/c or C3H mice were injected intrade...
متن کاملHapten-specific Tolerance
The induction of tolerance in guinea pigs with a 2,4-dinitrophenyl (DNP) derivative of a copolymer of copolymer of D-glutamic acid and D-lysine (D-GL) leads to a preferential depression of the capacity to produce high affinity anti-DNP antibody in response to immunization with DNP-guinea pig albumin. Thus, immunization 2 wk after tolerance induction with 3 mg of DNP-D-GL results in an immune re...
متن کاملThe induction of hapten-specific immunological tolerance and immunity in B lymphocytes. VI. Differential tolerance susceptibility in adult spleen as a function of B-cell maturation level
The maturation level of the B-lymphocyte subpopulations involved in trinitrophenyl (TNP)-specific immunological tolerance in adult mice induced by the injection of trinitrobenzenesulfonic acid (TNBS) was investigated using in vitro antigen-specific and nonspecific polyclonal stimulation. The maturity of the B-cell subsets being studied was defined by the antigen or polyclonal activator which ev...
