IL-6-mediated environmental conditioning of defective Th1 differentiation dampens antitumour immune responses in old age

H Tsukamoto, S Senju, K Matsumura, SL Swain… - Nature …, 2015 - nature.com
Decline in immune function and inflammation concomitantly develop with ageing. Here we
focus on the impact of this inflammatory environment on T cells, and demonstrate that in …

Targeting macrophages rescues age‐related immune deficiencies in C57 BL/6J geriatric mice

C Jackaman, HG Radley‐Crabb, Z Soffe… - Aging cell, 2013 - Wiley Online Library
Changes to innate cells, such as macrophages and myeloid‐derived suppressor cells
(MDSC s), during aging in healthy or tumor‐bearing hosts are not well understood. We …

IL-10–producing Tfh cells accumulate with age and link inflammation with age-related immune suppression

M Almanan, J Raynor, I Ogunsulire, A Malyshkina… - Science …, 2020 - science.org
Aging results in profound immune dysfunction, resulting in the decline of vaccine
responsiveness previously attributed to irreversible defects in the immune system. In …

CD4 T cell defects in the aged: causes, consequences and strategies to circumvent

W Zhang, V Brahmakshatriya, SL Swain - Experimental gerontology, 2014 - Elsevier
Aging leads to reduced immunity, especially adaptive responses. A key deficiency is the
poor ability to mount robust antibody response. Although intrinsic alterations in B cells with …

IL-2/CD40-activated macrophages rescue age and tumor-induced T cell dysfunction in elderly mice

C Jackaman, DE Dye, DJ Nelson - Age, 2014 - Springer
The role of macrophages and their interactions with T cells during aging is not well
understood. We determined if activating elderly-derived macrophages could rescue age …

Mononuclear phagocyte-derived IL-10 suppresses the innate IL-12/IFN-γ axis in lung-challenged aged mice

BC Chiu, VR Stolberg, SW Chensue - The Journal of Immunology, 2008 - journals.aai.org
Previously, we reported that IL-10-producing mononuclear phagocytes increase in lungs of
aged mice, causing impaired innate cytokine expression. Since dendritic cells (DCs) …

The aged microenvironment contributes to the age‐related functional defects of CD4 T cells in mice

JS Lefebvre, AC Maue, SM Eaton, PA Lanthier… - Aging cell, 2012 - Wiley Online Library
CD4 T cells, and especially T follicular helper cells, are critical for the generation of a robust
humoral response to an infection or vaccination. Importantly, immunosenescence affects …

The aged lymphoid tissue environment fails to support naïve T cell homeostasis

BR Becklund, JF Purton, C Ramsey, S Favre, TK Vogt… - Scientific reports, 2016 - nature.com
Aging is associated with a gradual loss of naïve T cells and a reciprocal increase in the
proportion of memory T cells. While reduced thymic output is important, age-dependent …

Effects of aging on T cell function

L Haynes, AC Maue - Current opinion in immunology, 2009 - Elsevier
Immunosenescence influences many components of the immune system. Most importantly,
profound changes in T cell function are evident in older individuals. The impact of aging on …

From naive to effector‐alterations with aging

PJ Linton, L Haynes, L Tsui, X Zhang… - Immunological …, 1997 - Wiley Online Library
We have used a T‐cell receptor transgenic mouse model to study the role of antigen in the
changes that occur as T cells age. We find that the characteristic shift in the CD4 population …
