Concepts of GPCR-controlled navigation in the immune system

, 2019
G-protein-coupled receptor (GPCR) signaling is essential for the spatiotemporal control of leukocyte dynamics during immune responses. For efficient navigation through mammalian tissues, most leukocyte types express more than one GPCR on their surface ...

Gorab deficiency in skin dermis accelerates aging and is associated with dysregulation of RCHY1‐mediated P53 ubiquitination

Animal Models and Experimental Medicine, EarlyView.
Based on a dermis fibroblast Gorab knockout mouse model, this study revealed that Gorab deficiency promotes skin aging by influencing RCHY1, causing a decrease in P53 ubiquitination, damaging the activity of HDAC2, further resulting in the accumulation of aging‐related proteins (P53, P21, P16) and a reduction in extracellular matrix (ECM) components ...

Antibody durability is influenced by interleukin-2 production by undifferentiated memory T helper cells and extensive B cell clonal expansion

Cell Reports
Summary: SARS-CoV-2-neutralizing antibody titers serve as immune correlates of protection against COVID-19; however, the durability varies among vaccinees.

Helper T cell subsets: Development, function and clinical role in hypersensitivity reactions in the modern perspective

Heliyon
Helper T cells are traditionally classified into T helper 1 (TH1) and T helper 2 (TH2). The more recent discoveries of T helper 17 (TH17), follicular helper T cells (TFH) and regulatory T cells (Treg) enhanced our understanding on the mechanisms of ...

Recycling probability and dynamical properties of germinal center reactions

, 2001
We introduce a new model for the dynamics of centroblasts and centrocytes in a germinal center. The model reduces the germinal center reaction to the elements considered as essential and embeds proliferation of centroblasts, point mutations of the ...

Equine models in translational medicine: A comparative approach to human health

Animal Models and Experimental Medicine, EarlyView.
This diagram summarizes and contrasts rodent and equine models, outlining their strengths, limitations, and applications. Horses offer naturally occurring diseases, genetic and physiological similarities to humans, and suitability for longitudinal and clinical‐scale studies.

Antigen Complexed with a TLR9 Agonist Bolsters c-Myc and mTORC1 Activity in Germinal Center B Lymphocytes. [PDF]

, 2019
The germinal center (GC) is the anatomical site where humoral immunity evolves. B cells undergo cycles of proliferation and selection to produce high-affinity Abs against Ag. Direct linkage of a TLR9 agonist (CpG) to a T-dependent Ag increases the number
