Analysis of lipopolysaccharide antigens of Treponema hyodysenteriae [PDF]

, 1989
Lipopolysaccharide (LPS) extracts obtained from Treponema hyodysenteriae of serogroups A, B, D and E, and from T. innocens were examined by SDS-polyacrylamide gel electrophoresis (SDS-PAGE), silver-staining, and immunoblotting with hyperimmune rabbit ...

CD86‐Positive Mature Tertiary Lymphoid Structures Are Associated With CD8+ T‐Cell Infiltration and Favorable Clinical Outcomes in Pancreatic Ductal Adenocarcinoma

Annals of Gastroenterological Surgery, EarlyView.
CD86‐positive mature tertiary lymphoid structures were associated with increased intratumoral CD8+ T‐cell infiltration, a higher proportion of Granzyme B‐expressing CD8+ T cells in an exploratory analysis, and favorable clinical outcomes in pancreatic ductal adenocarcinoma.

Non-precipitating protein antigens

, 1941
When some protein antigens are heated with serologically unspecific proteins they cease to be precipitated by their antisera, and their behaviour in vitro approximates to that of non–precipitating haptens.

Autoreactivity Versus Autoimmunity: Characteristics of Autoantigen‐Specific CD4 T Cells in Rheumatoid Arthritis and Health

Arthritis &Rheumatology, EarlyView.
Objective CD4 T cells specific for citrullinated (cit) peptides are key players in rheumatoid arthritis (RA) immunopathogenesis. Characterizing these cells and identifying features of healthy and RA‐associated autoreactivity will provide valuable insight into disease mechanisms and form the basis of immune state biomarkers to facilitate the next ...

CD28

, 2018
CD28 was identified in early 1980s by Martin and colleagues by monoclonal antibodies recognizing a 44 kDa protein on the surface of human T lymphocytes (Martin et al. 1980). Further experiments from Gmunder and Lessener evidenced the crucial role of this

Dnmt3a Mutations Limit Normal and Autoreactive CD4+ T Follicular Helper Responses and Attenuate T Cell–Driven Joint Inflammation

Arthritis &Rheumatology, EarlyView.
Objective Somatic DNMT3A mutations are the most common drivers of clonal hematopoiesis in patients with rheumatoid arthritis (RA) and have been associated with seropositive disease and increased markers of inflammation. These mutations are predominantly hypomorphic or dominant‐negative, reducing DNMT3A function.

Growth of human regulatory CD4+ T cells is more tightly controlled than effector T cells due to distinctive molecular programming

iScience
Summary: Foreign and self-antigens activate CD4+ conventional and regulatory T cells (Tregs) to promote immunity and tolerance, respectively. These cell populations, which depend on interleukin-2 (IL-2), are being expanded and engineered in vitro for ...

A CARMIL2 gain-of-function mutation suffices to trigger most CD28 costimulatory functions in vivo

International audienceNaive T cell activation requires both TCR and CD28 signals. The CARMIL2 cytosolic protein enables CD28-dependent activation of the NF-κB transcription factor via its ability to link CD28 to the CARD11 adaptor protein.

Deep Immunophenotyping Reveals Distinct Immune Signatures in Axial Spondyloarthritis and Psoriatic Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) are overlapping yet distinct conditions within the SpA spectrum. As divergent immunophenotypes may influence disease course and therapeutic response, we compared immune cell subsets, cytokine profiles, and inflammatory mediators.

Endogenous human cytomegalovirus gB is efficiently presented by MHC class II molecules to CD4+ CTL [PDF]

, 2005
Human cytomegalovirus (HCMV) infects endothelial, epithelial, and glial cells in vivo. These cells can express MHC class II proteins, but are unlikely to play important roles in priming host immunity.
