Membrane-bound immunoglobulins of peripheral blood B lymphocytes and of lymphocytes from an IgG chronic lymphocytic leukemia showed restriction to one immunoglobulin class, one IgG subclass, and one Gm allotype. Certain antigens in the C-terminal part of IgG Fc were not exposed on the cell surface.

The relative susceptibility of neonatal and adult murine splenocytes to induction of B-cell tolerance was studied in vitro. Adult cells required approximately 1,000-fold more trinitrophenyl-human gamma globulin to be rendered tolerant than did cells from 9- to 12-day-old neonates. The potential effects of suppressor T cells were excluded by pretreating the cultured B cells with anti-Thy-1 and C...

immunoglobulin e is one of the five classes of immonoglobulins that plays an important role in allergic diseases. production of monoclonal antibodies by a single clonotype against different epitopes of immunoglobulin e has high priority in development of diagnostic kits. in this study, an attempt was made to produce monoclonal antibodies against human immunoglobulin e. balb/c mice were immunize...

OBJECTIVE To compare the inflammatory factors and immune functions of patients with lung cancer and pulmonary ground-glass attenuation. PATIENTS AND METHODS A total of 108 patients with pulmonary sarcoidosis treated in our hospital were selected and randomly divided into lung cancer group (Group A, n=32), diffuse ground-glass nodule group (Group B, n=35) and solitary ground-glass nodule group...

Vpre-B and lambda 5 genes, respectively, encode V-like and C-like domains of a surrogate immunoglobulin light chain (psi L). Such psi L complex is expressed in early progenitor B (pro-B) cells, before conventional immunoglobulin heavy (microH) and light (L) chains are produced. We raised a wide panel of monoclonal antibodies (mAbs) against soluble recombinant Vpre-B proteins to study early even...

Vpre-B and k5 genes, respectively, encode V-like and C-like domains of a surrogate immunoglobulin light chain (~L). Such WL complex is expressed in early progenitor B (pro-B) cells, before conventional immunoglobulin heavy (/~H) and light (L) chains are produced. We raised a wide panel of monoclonal antibodies (mAbs) against soluble recombinant Vpre-B proteins to study early events in httman B ...

Syphilis is a sexually transmitted disease with prominent cutaneous manifestations. A frequent histologic feature of syphilis the presence B-cells and plasma cells, which are infrequently observed in other acute inflammatory diseases skin. To determine regulation this unique environment syphilis, we performed bulk RNA-seq on formalin-fixed, paraffin-embedded biopsies obtained from 9 patients se...

Anti-idiotype reagents that recognize a common idiotype associated with the combining site of antibodies to hepatitis B surface antigen (anti-HBs) were used to manipulate the immune response to hepatitis B surface antigen in BALB/c mice. The injection of antibodies to the idiotype before antigenic stimulation resulted in an increase in the number of cells secreting immunoglobulin M antibodies t...

The importance of antibody immunity in protection against Cryptococcus neoformans remains unresolved. We measured serum C neoformans-specific and total antibody levels and peripheral blood B cell subsets of 12 previously healthy patients with cryptococcosis (cases) and 21 controls. Before and after adjustment for age, sex, and race, cryptococcal capsular polysaccharide immunoglobulin G was high...

in helping pokeweed mitogen-induced immunoglobulin production by normal B cells. However, when normal T cells were co-cultured with B cells from patients with Hodgkin's disease, spontaneous IgG synthesis declined, whereas the addition of patient T cells Received for publication 21 May 1982 and in revisedform 26 November 1982. to normal B cells resulted in an increase of spontaneous IgG synthesi...
