IgD(+) age-associated B cells are the progenitors of the main T-independent B cell response to infection that generates protective Ab and can be induced by an inactivated vaccine in the aged
Kugler-Umana, O., Zhang, W., Kuang, Y., Liang, J., Castonguay, C. H., Tonkonogy, S. L., … Swain, S. L. (2022, September 2). AGING CELL.
author keywords: adaptive immunity; age-associated B cells; aging; influenza; TLR signals
MeSH headings : Animals; Humans; Mice; Antibodies, Viral; Immunoglobulin D; Immunoglobulin G; Immunoglobulin M; Influenza Vaccines; Influenza, Human; Toll-Like Receptor 7; Toll-Like Receptor 9; Vaccines, Inactivated; B-Lymphocytes; T-Lymphocytes
TL;DR:
It is found that in response to influenza, IgD+CD21-CD23-ABC are the precursors of iABC, which is likely the naïve B cells with the potential to become Ab-secreting cells and to provide protection from infection in the aged.

Transient activation of mucosal effector immune responses by resident intestinal bacteria in normal hosts is regulated by interleukin-10 signalling
IMMUNOLOGY, 148(3), 304–314.
author keywords: germ-free mice; interleukin-10; resident bacteria
MeSH headings : Animals; Antigens, Bacterial / immunology; B-Lymphocytes / immunology; Cells, Cultured; Colitis / etiology; Colitis / immunology; Disease Models, Animal; Escherichia coli / immunology; Escherichia coli Infections / complications; Escherichia coli Infections / immunology; Immunity, Mucosal; Interferon-gamma / metabolism; Interleukin-10 / genetics; Interleukin-10 / metabolism; Intestines / immunology; Intestines / microbiology; Lymphocyte Activation; Mice; Mice, 129 Strain; Mice, Knockout; Signal Transduction; Th1 Cells / immunology

Interleukin 2, but not other common gamma chain-binding cytokines, can reverse the defect in generation of CD4 effector T cells from naive T cells of aged mice
JOURNAL OF EXPERIMENTAL MEDICINE, 190(7), 1013–1023.
author keywords: T cell receptor transgenic; CD4 cells; aging; IL-2; gamma c-binding cytokines
MeSH headings : Aging / immunology; Animals; CD4-Positive T-Lymphocytes / cytology; CD4-Positive T-Lymphocytes / immunology; Cell Differentiation / drug effects; Cell Differentiation / immunology; Cells, Cultured; Cytokines / biosynthesis; Cytokines / pharmacology; H-2 Antigens / immunology; Interferon-gamma / biosynthesis; Interferon-gamma / pharmacology; Interleukin-2 / biosynthesis; Interleukin-2 / pharmacology; Interleukin-4 / biosynthesis; Interleukin-4 / pharmacology; Interleukin-5 / biosynthesis; Interleukin-5 / pharmacology; Lymphocyte Activation; Mice; Mice, Inbred C57BL; Mice, Inbred Strains; Mice, Transgenic; Receptors, Antigen, T-Cell, alpha-beta / genetics; Receptors, Antigen, T-Cell, alpha-beta / immunology; Recombinant Proteins / pharmacology; T-Lymphocytes / cytology; T-Lymphocytes / immunology; Th1 Cells / immunology; Th2 Cells / immunology
TL;DR:
The results indicate that responding naive CD4 cells from aged mice, compared with cells from young mice, make less interleukin (IL)-2, expand poorly between days 3 to 5, and give rise to fewer effectors with a less activated phenotype and reduced ability to produce cytokines, suggesting that the effect of aging on IL-2 production is reversible only in the presence of exogenous IL-1.

Blockade of both L-selectin and alpha(4) integrins abrogates naive CD4 cell trafficking and responses in gut-associated lymphoid organs
INTERNATIONAL IMMUNOLOGY, 10(7), 961–968.
author keywords: adhesion molecules; CD4 T lymphocytes; homing; recirculation
MeSH headings : Animals; Antibodies, Monoclonal / pharmacology; Antigens, CD / physiology; CD4-Positive T-Lymphocytes / immunology; Endothelium, Lymphatic / immunology; Female; Integrin alpha4; L-Selectin / physiology; Lymph Nodes / cytology; Lymph Nodes / immunology; Lymphocyte Activation / physiology; Male; Mice; Mice, Inbred C57BL; Peyer's Patches / cytology; Peyer's Patches / immunology; Rats
TL;DR:
Recirculation of naive CD4 cells through tissues where entry is controlled through HEV is essential for the local generation of primary responses, and a blockade of both adhesion pathways on the recirculation is examined.

L-selectin is not essential for naive CD4 cell trafficking or development of primary responses in Peyer's patches
EUROPEAN JOURNAL OF IMMUNOLOGY, 27(5), 1140–1146.
author keywords: CD4; Peyer's patch; L-selectin; trafficking
MeSH headings : Animals; Antibodies, Monoclonal / pharmacology; CD4-Positive T-Lymphocytes / immunology; CD4-Positive T-Lymphocytes / metabolism; Cell Movement / immunology; L-Selectin / immunology; L-Selectin / physiology; Lymph Nodes / immunology; Lymphocyte Activation; Lymphocyte Depletion; Mice; Mice, Inbred C57BL; Mice, Transgenic; Peyer's Patches / cytology; Peyer's Patches / immunology
TL;DR:
It is shown that anti‐L‐selectin antibody, MEL‐14, inhibited homing of a rigorously purified, homogenous population of naive CD4 cells into both of these tissues as well as peripheral lymph nodes, directly demonstrating a role for this receptor in regulating entry into gut‐associated sites.

HELPER T-CELL SUBSETS - PHENOTYPE, FUNCTION AND THE ROLE OF LYMPHOKINES IN REGULATING THEIR DEVELOPMENT
[Review of ]. IMMUNOLOGICAL REVIEWS, 123, 115–144.
MeSH headings : Animals; CD4-Positive T-Lymphocytes / immunology; Humans; Immunophenotyping; Lymphocyte Activation; Lymphokines / immunology; T-Lymphocyte Subsets / immunology; T-Lymphocytes, Helper-Inducer / immunology
TL;DR:
The studies suggest these emerging memory cells may be phenotypically unique and postulate that they are specialized to become a "long-lived" population of memory cells that will persist indefinitely as a protective population of increased frequency for the antigen encountered and which is also able to respond more rapidly and effectively.
