Using chemical germ-line mutagenesis, we screened mice for defects in the humoral immune response to a type II T-independent immunogen and an experimental alphavirus vector. A total of 26 mutations that impair humoral immunity were recovered, and 19 of these mutations have been positionally cloned. Among the phenovariants were bumble, cellophane, and Worker(More)
B lymphopoiesis begins in the fetal liver, switching after birth to the bone marrow, where it persists for life. The unique developmental outcomes of each phase are well documented, yet their molecular requirements are not. Here we describe two allelic X-linked mutations in mice that caused cell-intrinsic arrest of adult B lymphopoiesis. Mutant fetal liver(More)
Nitric oxide (NO) is a gasotransmitter that impacts fundamental aspects of neuronal function in large measure through S-nitrosylation, a redox reaction that occurs on regulatory cysteine thiol groups. For instance, S-nitrosylation regulates enzymatic activity of target proteins via inhibition of active site cysteine residues or via allosteric regulation of(More)
BACKGROUND Painful neuropathy is a dose-limiting side effect in cancer chemotherapy. To characterize this phenomenon, we examined pain behavior and analgesic actions in a mouse model of cisplatin polyneuropathy. METHODS Male C57BL/6 mice received intraperitoneal cisplatin or saline (2.3 mg/kg/d) every other day 6 times over 2 weeks for a total dose of(More)
Using an environmentally sensitized genetic screen we identified mutations that cause inflammatory colitis in mice. The X-linked Klein-Zschocher (KLZ) mutation created a null allele of Yipf6, a member of a gene family believed to regulate vesicular transport in yeast, but without known functions in mammals. Yipf6 is a five transmembrane-spanning protein(More)
Null alleles of the gene encoding NEMO (NF-kappaB essential modulator) are lethal in hemizygous mice and men, whereas hypomorphic alleles typically cause a syndrome of immune deficiency and ectodermal dysplasia. Here we describe an allele of Ikbkg in mice that impaired Toll-like receptor signaling, lymph node formation, development of memory and regulatory(More)
Microsatellite repeat expansions in DNA produce pathogenic RNA species that cause dominantly inherited diseases such as myotonic dystrophy type 1 and 2 (DM1/2), Huntington's disease, and C9orf72-linked amyotrophic lateral sclerosis (C9-ALS). Means to target these repetitive RNAs are required for diagnostic and therapeutic purposes. Here, we describe the(More)
