Autophagy enhances NFκB activity in specific tissue macrophages by sequestering A20 to boost antifungal immunity.
(Nat Commun, 2015-01-22)Immune responses must be well restrained in a steady state to avoid excessive inflammation. However, such restraints are quickly removed to exert antimicrobial responses. Here we report a role of autophagy in an early host ... -
Complement C4 inhibits systemic autoimmunity through a mechanism independent of complement receptors CR1 and CR2.
(J Exp Med, 2000-11-06)The complement system enhances antibody responses to T-dependent antigens, but paradoxically, deficiencies in C1 and C4 are strongly linked to autoantibody production in humans. In mice, disruption of the C1qa gene also ... -
Genotypic analysis of B cell colonies by in situ hybridization. Stoichiometric expression of three VH families in adult C57BL/6 and BALB/c mice.
(J Exp Med, 1987-07-01)The filter paper disc method for cloning inducible lymphocytes was used to census the splenic B cell population of C57BL/6 and BALB/c mice for the expression of three VH gene-families, VH X-24, -Q52, and -J558. B cell colonies, ... -
In situ studies of the primary immune response to (4-hydroxy-3-nitrophenyl)acetyl. I. The architecture and dynamics of responding cell populations.
(J Exp Med, 1991-05-01)After primary immunization with an immunogenic conjugate of (4-hydroxy-3-nitrophenyl)acetyl, two anatomically and phenotypically distinct populations of antibody-forming cells arise in the spleen. As early as 2 ... -
In situ studies of the primary immune response to (4-hydroxy-3-nitrophenyl)acetyl. III. The kinetics of V region mutation and selection in germinal center B cells.
(J Exp Med, 1993-10-01)In the murine spleen, germinal centers are the anatomic sites for antigen-driven hypermutation and selection of immunoglobulin (Ig) genes. To detail the kinetics of Ig mutation and selection, 178 VDJ sequences from ... -
In situ studies of the primary immune response to (4-hydroxy-3-nitrophenyl)acetyl. IV. Affinity-dependent, antigen-driven B cell apoptosis in germinal centers as a mechanism for maintaining self-tolerance.
(J Exp Med, 1995-12-01)Germinal centers (GCs) are the sites of antigen-driven V(D)J gene hypermutation and selection necessary for the generation of high affinity memory B lymphocytes. Despite the antigen dependence of this reaction, injection ... -
M-HIFU inhibits tumor growth, suppresses STAT3 activity and enhances tumor specific immunity in a transplant tumor model of prostate cancer.
(PLoS One, 2012)OBJECTIVE: In this study, we explored the use of mechanical high intensity focused ultrasound (M-HIFU) as a neo-adjuvant therapy prior to surgical resection of the primary tumor. We also investigated the role of signal transducer ... -
Multiple phenotypic changes in mice after knockout of the B3gnt5 gene, encoding Lc3 synthase--a key enzyme in lacto-neolacto ganglioside synthesis.
(BMC Dev Biol, 2010-11-18)BACKGROUND: Ganglioside biosynthesis occurs through a multi-enzymatic pathway which at the lactosylceramide step is branched into several biosynthetic series. Lc3 synthase utilizes a variety of galactose-terminated glycolipids ... -
Relaxed negative selection in germinal centers and impaired affinity maturation in bcl-xL transgenic mice.
(J Exp Med, 1999-08-02)The role of apoptosis in affinity maturation was investigated by determining the affinity of (4-hydroxy-3-nitrophenyl)acetyl (NP)-specific antibody-forming cells (AFCs) and serum antibody in transgenic mice that overexpress ... -
Spectral diffusion: an algorithm for robust material decomposition of spectral CT data.
(Phys Med Biol, 2014-11-07)Clinical successes with dual energy CT, aggressive development of energy discriminating x-ray detectors, and novel, target-specific, nanoparticle contrast agents promise to establish spectral CT as a powerful functional ... -
Thymic requirement for cyclical idiotypic and reciprocal anti-idiotypic immune responses to a T-independent antigen.
(J Exp Med, 1980-02-01)The role of the thymus in the cyclical appearance of the dominant idiotype of the myeloma protein secreted by the TEPC-15 plasmacytoma (T-15)-bearing plaque-forming cells (PFC) and anti-idiotypic cells (i.e., cells with ... -
TSC1 Promotes B Cell Maturation but Is Dispensable for Germinal Center Formation.
(PLoS One, 2015)Accumulating evidence indicates that the tuberous sclerosis complex 1 (TSC1), a tumor suppressor that acts by inhibiting mTOR signaling, plays an important role in the immune system. We report here that TSC1 differentially ...
