Increased numbers of CD5+ B lymphocytes with a regulatory phenotype in spondylarthritis

, 2012
Objective Whether and how B lymphocytes contribute to the pathogenesis of spondylarthritis (SpA), a seronegative arthritis associated with gut inflammation, remains unknown.

Intestinal newborn regulatory B cell antibodies modulate microbiota communities

International audienceThe role of immunoglobulins produced by IL-10-producing regulatory B cells remains unknown. We found that a particular newborn regulatory B cell population (nBreg) negatively regulates the production of immunoglobulin M (IgM) via IL-

Trypanosome non-specific antibody responses during trypanosoma congolense infection of cattle

, 1998
DissertationEXPERIMENT ONE Trypanosome infections of cattle are characterized by concomitant increase in serum IgM, development of antibodies reacting with non-trypanosome antigens and an increase in the proportion of CD5+ B cells in peripheral blood and

Beneficial effect of Salmonella typhimurium infection and of immunoglobulins from S. typhimurium-infected mice on the autoimmune disease of (NZB × NZW)F1 mice

, 1996
Various infections can precede or aggravate autoimmune diseases. Yet a beneficial effect of infection has also been described and various mechanisms have been postulated to explain this effect.

Παραγωγή και μελέτη μονοκλωνικών αντισωμάτων από ασθενείς με νεοπλάσματα από ώριμα Β λεμφοκύτταρα [PDF]

, 2018
Η μελέτη των ανοσοσφαιρινών των Β κυτταρικών υποδοχέων σε μοριακό επίπεδο έχει συμβάλει αποφασιστικά στην κατανόηση της μοριακής βάσης κακοηθειών ώριμων Β λεμφοκυττάρων (B cell non-Hodgkin lymphomas, B-NHLs) και θεμελίωσε την ιδέα της αντιγονικής ...

Μελέτη βιολογικής δράσης ανθρώπινων μονοκλωνικών φυσικών αντισωμάτων τάξης IgM στον καρκίνο του μαστού

, 2022
Τα φυσικά αντισώματα (ΦΑ/ Natural Antibodies, NAbs) παράγονται χωρίς προηγούμενη εξωγενή αντιγονική διέγερση και ανευρίσκονται στον ορό υγιών ατόμων. Κύριο χαρακτηριστικό των ΦΑ είναι η πολυδραστικότητα η οποία αποτελεί την ειδοποιό διαφορά σε σχέση με ...

Antigen-specific CD4+ T-B cell interplay induces a robust, polyreactive systemic immunoglobulin response to commensal bacteremia.

, 2020
The impact of cognate CD4+ T cell help on the systemic antibody response during commensal bacteremia was assessed in detail in this thesis. To specifically evaluate cognate T cell-B cell interactions, we utilized a genetically modified commensal E. coli strain that expressed gp61, an additional T helper epitope, in its outer membrane ompC protein (E ...
