Suppressor cell-mediated neutropenia in Felty's syndrome.

Abdou, N I, NaPombejara, C, Balentine, L, Abdou, N L

The mechanism of neutropenia in Felty's Syndrome (FS) was tested. The suppressor capacity of mononuclear cells from patients with FS on normal bone marrow granulopoiesis was tested by the in vitro...

The secondary antibody response in tissue culture: IV. Studies of the in vivo and in vitro antigenicity of native, aggregate-free and aggregated human gamma globulin in rabbits*

Abdou, N. I., Richter, M.

The antigenicity of native, aggregate-free and heat-aggregated HGG was investigated in vivo and in vitro, using the cell culture and fragment culture systems. Although the aggregate-free material...

Cationic and high affinity serum IgG anti-dsDNA antibodies in active lupus nephritis.

Suenaga, R, Abdou, N I

To investigate differences between cationic anti-dsDNA antibodies during active and inactive nephritis, low- and high-affinity IgG anti-dsDNA antibodies were prepared from sera of a lupus patient and...

T and B lymphocytes in multiple sclerosis.

Lisak, R P, Levinson, A I, Zweiman, B, Abdou, N I

The percentage and total number of E and EAC rosettes, as indicators of T and B lymphocytes respectively, were studied in the blood of subjects with multiple sclerosis (MS) and normals. MS patients...

Anti-idiotypic antibody against anti-DNA in sera of laboratory personnel exposed to lupus sera or nucleic acids.

Hatfield, M, Evans, M, Suenaga, R, Hassanein, K M, Abdou, N I

We tested for anti-DNA, anti-idiotypic, antinuclear, and lymphocytotoxic antibodies in the sera of three groups of normals: volunteers never exposed to lupus sera or nucleic acids (group I), research...

Anti-immunoglobulins in multiple myeloma

Abdou, N. I., Abdou, Nancy L.

Human myeloma cells isolated from bone marrow aspirates by sucrose density gradients and cultured in vitro were shown to undergo proliferation and increased DNA synthesis upon incubation with...

Immunoglobulin receptors on human leucocytes. III. Comparative study of human bone marrow and blood B cells: role of IgM receptors

Abdou, N. I., Abdou, Nancy L.

A comparative study of B cells present in human bone marrow and blood was performed. In both compartments the cells carrying the Ig receptors were found to be small mononuclear cells. Predominance of...

Effects of azathioprine therapy on bone marrow-dependent and thymus-dependent cells in man

Abdou, N. I., Zweiman, B., Casella, S. R.

The in vitro immunologic parameters of both bone marrow-dependent (B) and thymus-dependent (T) cells of patients with no demonstrable immunologic abnormality and to whom only azathioprine (az) was...

CELLS INVOLVED IN THE IMMUNE RESPONSE : VII. THE DEMONSTRATION, USING ALLOTYPIC MARKERS, OF ANTIBODY FORMATION BY IRRADIATION-RESISTANT CELLS OF IRRADIATED RABBITS INJECTED WITH NORMAL ALLOGENEIC BONE MARROW CELLS AND SHEEP ERYTHROCYTES

Richter, M., Abdou, N. I.

Bone marrow cells obtained from rabbits of one allotype were injected into irradiated rabbits of a different allotype. The recipients were also injected with sheep red blood cells, and their spleen...
