Increased NFAT activity with dual CAR stimulation in CD19xCD22 CAR T-cells is associated with decreased exhaustion and improved survival [PDF]

open access: yesJournal for ImmunoTherapy of Cancer
Background Chimeric antigen receptor (CAR) T-cell therapy is effective in treating B-cell malignancies, however relapse due to lack of CAR persistence and antigen-modulated escape remains common. Multiple strategies to simultaneously target CD19 and CD22

The CD28-Transmembrane Domain Mediates Chimeric Antigen Receptor Heterodimerization With CD28 [PDF]

open access: yesFrontiers in Immunology, 2021
Anti-CD19 chimeric antigen receptor (CD19-CAR)-engineered T cells are approved therapeutics for malignancies. The impact of the hinge domain (HD) and the transmembrane domain (TMD) between the extracellular antigen-targeting CARs and the intracellular signaling modalities of CARs has not been systemically studied.

Cytomegalovirus infection in HIV-infected and uninfected individuals is characterized by circulating regulatory T cells of unconstrained antigenic specificity. [PDF]

open access: yesPLoS ONE, 2017
Cytomegalovirus (CMV) infection is associated with immune-suppression in immune-compromised hosts and old adults. We previously showed that ex vivo CMV restimulation of peripheral blood mononuclear cells (PBMC) of CMV-seropositive volunteers expanded CD4+

Common gamma chain cytokines promote rapid in vitro expansion of allo-specific human CD8+ suppressor T cells. [PDF]

open access: yesPLoS ONE, 2011
Human CD8(+) regulatory T cells, particularly the CD8(+)CD28(-) T suppressor cells, have emerged as an important modulator of alloimmunity. Understanding the conditions under which these cells are induced and/or expanded would greatly facilitate their ...

The Expression of CD28 and Its Synergism on the Immune Response of Flounder (Paralichthys olivaceus) to Thymus-Dependent Antigen

open access: yesFrontiers in Immunology, 2021
CD28 is well known as a critical T-cell costimulatory receptor involved in T cell activation by binding to its ligands. In this study, CD28 was cloned, and its expression profiles were characterized in flounder (Paralichthys olivaceus); variations of ...

Arming Cytokine-induced Killer Cells With Chimeric Antigen Receptors: CD28 Outperforms Combined CD28–OX40 “Super-stimulation” [PDF]

open access: yesMolecular Therapy, 2013
Cytokine-induced killer (CIK) cells raised interest for use in cellular antitumor therapy due to their capability to recognize and destroy autologous tumor cells in a HLA-independent fashion. The antitumor attack of CIK cells, predominantly consisting of terminally differentiated CD8(+)CD56(+) cells, can be improved by redirecting by a chimeric antigen

Investigating role of Mycobacterium tuberculosis secretory antigens in altering activation of T cell signaling events in Jurkat T cells

open access: yesInternational Journal of Mycobacteriology, 2020
Background: Mycobacterium tuberculosis is able to survive and persist as an intracellular pathogen by modulating its own metabolism and host immunity. The molecules and mechanisms utilized to accomplish this modulation are not fully understood.

Peripheral blood responses to specific antigens and CD28 in sarcoidosis [PDF]

open access: yesRespiratory Medicine, 2012
Potential antigens inducing sarcoid inflammation include mycobacterial and auto-antigens. Paradoxically, peripheral anergy to common recall antigens also occurs, possibly due to impaired dendritic cell or regulatory T-cell responses, or impaired T-cell co-stimulation.

miR‐21 sustains CD28 signalling and low‐affinity T‐cell responses at the expense of self‐tolerance

open access: yesClinical & Translational Immunology, 2021
Objective miR‐21 is highly expressed in iNKT and activated T cells, but its T‐cell autonomous functions are poorly defined. We sought to investigate the role of miR‐21 in the development and functions of T and iNKT cells, representing adaptive and innate‐

Costimulators expressed on human endothelial cells modulate antigen-dependent recruitment of circulating T lymphocytes

open access: yesFrontiers in Immunology, 2022
Endothelial cells (ECs) can present antigens to circulating effector memory T cells (TEM) and to regulatory T cells (T regs), triggering antigen-specific extravasation at specific sites where foreign antigens are introduced, e.g.
