Intestinal metaplasia (IM) foci in 19 antral and 14 fundal gastric biopsies from patients with chronic atrophic gastritis were studied immunohistochemically for the presence of CALLA antigen. In only 2 cases were metaplastic glands completely negative, in 14 cases they were all positive, and in 17
CALLA is a 100,000-dalton surface glycoprotein expressed by malignant cells of patients with clinically important subtypes of acute leukemia. Incubation of human leukemic cells expressing CALLA with specific monoclonal antibody (J5) at 37 degrees C causes rapid and selective internalization and
First described on pre-B leukemia cells, the common acute lymphoblastic leukemia antigen (cALLa) is also expressed on glioma cells in vitro. Its identity to neutral endopeptidase (NEP) (E.C.3.24.11) was corroborated by our finding that cALLa positive glioma cells had NEP activity. To study cALLa/NEP
The histological diagnosis of hepatocellular carcinoma (HCC) can be complicated by difficulty in differentiation from cholangiocarcinoma and metastatic carcinoma. Immunohistochemical stains currently in use are suboptimal in terms of specificity and sensitivity. Using cDNA array analysis for
We describe a newly-made murine monoclonal antibody to the common acute lymphoblastic leukemia antigen (CALLA), named SHB-10. The antigen detected by SHB-10 has a molecular weight of about 105 kDa. This antibody is very similar to that of conventional anti-CD10 Ab on indirect flowcytometric analysis
Fetal hematopoietic cells that express the common acute lymphoblastic leukemia antigen (CALLA) were purified from both fetal liver and fetal bone marrow by immune rosetting with sheep erythrocytes coated with rabbit anti-mouse immunoglobulin and by fluorescence-activated cell sorting. Dual
BackgroundConcurrent chemoradiotherapy is the standard of care for locally advanced cervical cancer. Concurrent chemoradiotherapy with programmed blockade of the cell death-1/programmed cell death-ligand 1 pathway may promote a more immunogenic environment through increased phagocytosis, cell death,
•CALLA (NCT03830866) is a randomized, international, double-blind, placebo-controlled study.•Immunotherapy-naïve patients with adenocarcinoma or cervical carcinoma are being enrolled.•CALLA is one of the largest trials in this patient population.
A panel of monoclonal antibodies applied to frozen sections of non-Hodgkin's lymphomas was used to establish clear-cut differences among the different entities of malignant lymphomas of germinal centre cell origin. 51 cases (18 centrocytic, 25 centroblastic-centrocytic and 8 centroblastic lymphomas)
Five human malignant non-T lymphoid cell lines have been established. THP-4 and THP-7 were derived from two children with common type acute lymphoblastic leukemia (ALL), THP-6 and THP-8 from two children with null cell type ALL and THP-9 from a child with malignant lymphoma. THP-4 was positive for
Using an indirect immunoperoxidase technique, we tested frozen specimens from 12 Wilms' tumors with monoclonal antibodies (MoAbs) reacting against a large panel of molecules including laminin, fibronectin, cytokeratin, vimentin, villin, CD24, CALLA/CD10, CR1, CD26, class I and class II major
Adult and fetal human kidneys were investigated for the reactivities of monoclonal antibodies, BA-1, BA-2 and BA-3 against human leukocytes. In developing metanephros, their reactivities changed reflecting the stage of nephrogenesis. Thus BA-1 stained both metanephric blastema and ureteric bud.
We constructed a series of MAb heterodimers consisting of the J5 (anti-common acute lymphoblastic leukemia antigen [CALLA]) antibody and antibodies to a variety of structures present on the surface of activated human T cells, including CD3 antigen (T cell receptor-associated glycoproteins), CD2
Monoclonal antibodies were used in the indirect immunofluorescence test to assay the antigenic features of lymphoid cells in patients with lymphosarcoma. Some patients with progression of lymphoblastic lymphoma showed an increased content of T lymphocyte expressing early activation antigens,
