Spatial coordination of CD8 and TCR molecules controls antigen recognition by CD8⁺ T‐cells

FEBS Letters, 2005
The interactions between the TCR and peptides bound to class I MHC encoded molecules (pMHC) and a mechanism for CD8 cooperation in this process are reviewed. Observation of two TCR/CD8 populations with different lateral diffusion rate constants as well as two distinct association phases of class I MHC tetramers ((pMHC)4) with T‐cells suggest that the ...

CD4 and CD8 co-receptors modulate functional avidity of CD1b-restricted T cells

Nature Communications, 2022
CD4 and CD8 co-receptors are routinely used to define distinct functional and phenotypic lineages of T cells. Here the authors show CD4 and CD8 also modulate the functional avidity of the CD1b-restricted response to mycobacterial lipid ...

IL-4 receptor expression on CD8+ T cells is required for the development of protective memory responses against liver stages of malaria parasites. [PDF]

, 2005
IL-4 receptor (IL-4R)-deficient CD8+ T cells specific for the circumsporozoite protein of Plasmodium yoelii develop a severely impaired memory response after priming with parasites.

Coordinated responses to individual tumor antigens by IgG antibody and CD8+ T cells following cancer vaccination

Journal for ImmunoTherapy of Cancer, 2018
Background One of today’s greatest hurdles for cancer immunotherapy is the absence of information regarding which tumor antigens are already recognized by patients receiving immunotherapies, and whether those therapies then boost or generate an immune ...

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network

FEBS Letters, EarlyView.
Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

Avidity of influenza-specific memory CD8+ T-cell populations decays over time compromising antiviral immunity [PDF]

, 2012
Decline of cell-mediated immunity is often attributed to decaying T-cell numbers and their distribution in peripheral organs. This study examined the hypothesis that qualitative as well as quantitative changes contribute to the declining efficacy of CD8+

Dendritic cell cross-priming is essential for immune responses to Listeria monocytogenes. [PDF]

PLoS ONE, 2009
Cross-presentation is now recognized as a major mechanism for initiating CD8 T cell responses to virus and tumor antigens in vivo. It provides an elegant mechanism that allows relatively few Dendritic cells (DCs) to initiate primary immune responses ...

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Cyclophosphamide chemotherapy sensitizes tumor cells to TRAIL-dependent CD8 T cell-mediated immune attack resulting in suppression of tumor growth [PDF]

, 2009
Background: Anti-cancer chemotherapy can be simultaneously lymphodepleting and immunostimulatory. Pre-clinical models clearly demonstrate that chemotherapy can synergize with immunotherapy, raising the question how the immune system can be mobilized to ...

INNOVATIVE STRATEGIES TO IDENTIFY M. TUBERCULOSIS ANTIGENS AND EPITOPES USING GENOME-WIDE ANALYSES

Frontiers in Immunology, 2014
In view of the fact that only a small part of the Mtb expressome has been explored for identification of antigens capable of activating human T-cell responses, which is critically required for the design of better TB vaccination strategies, more emphasis
