Interferon regulatory factor 8-deficiency determines massive neutrophil recruitment but T cell defect in fast growing granulomas during tuberculosis [PDF]

open access: yes, 2013
Following Mycobacterium tuberculosis (Mtb) infection, immune cell recruitment in lungs is pivotal in establishing protective immunity through granuloma formation and neogenesis of lymphoid structures (LS).

Organogenesis of lymphoid tissues

open access: yesNature Reviews Immunology, 2003
The development of lymphoid organs depends on the correct expression of several molecules within a defined timeframe during ontogeny. Although this is an extremely complex process, with each secondary lymphoid tissue requiring subtly different signals, a common framework for lymphoid development is beginning to emerge. Drawing on studies of lymph nodes,

Lymphoid tissue inducer cells [PDF]

open access: yesCurrent Biology, 2011
What are they? Lymphoid tissue inducer (LTi) cells are a hematopoietic cell type with critical roles in the immune system during both the embryonic and adult stages of development. Their distinguishing features are expression of RORγt and IL-7Rα in the absence of lineage markers (e.g. CD3, CD19, B220, CD11c, Gr-1).

IL-15 sustains IL-7R-independent ILC2 and ILC3 development [PDF]

open access: yes, 2017
The signals that maintain tissue-resident innate lymphoid cells (ILC) in different microenvironments are incompletely understood. Here we show that IL-7 receptor (IL-7R) is not strictly required for the development of any ILC subset, as residual cells ...

Microchimerism, dendritic cell progenitors and transplantation tolerance [PDF]

open access: yes, 1995
The recent discovery of multilineage donor leukocyte microchimerism in allograft recipients up to three decades after organ transplantation implies the migration and survival of donor stem cells within the host.

Formation of immune structures in small intestine of Muscovy ducks (Cairina moschata)

open access: yesTheoretical and Applied Veterinary Medicine, 2020
Of particular importance in our time is the detailed study of morphology, physiology and biochemistry, the digestive system of new poultry crosses, which is the biological basis for the development of complete feeding and improving the productive ...

Possible role of GADD45γ methylation in diffuse large B-cell Lymphoma: Does it affect the progression and tissue involvement? [PDF]

open access: yes, 2015
Objective: Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma among adults and is characterized by heterogeneous clinical, immunophenotypic, and genetic features.

Morphology of the digestive canal organs and their immune formations in the mulard ducks

open access: yesUkrainian Journal of Veterinary Sciences, 2022
It is known that in the immune formations of the digestive canal of birds, which belong to the peripheral organs of hematopoiesis and lymphopoiesis, differentiation of T- and B-lymphocytes occurs under the influence of antigens that cause the development

The expression of the Hodgkin's disease associated antigen Ki-1 in reactive and neoplastic lymphoid tissue: evidence that Reed-Sternberg cells and histiocytic malignancies are derived from activated lymphoid cells.

open access: yesBlood, 1985
Ki-1 is a monoclonal antibody (raised against a Hodgkin's disease-derived cell line) that, in biopsy tissue affected by Hodgkin's disease, reacts selectively with Reed-Sternberg cells.
