Chemokine receptors are G-protein-coupled, seven-transmembrane-spanning surface receptors that play key roles in cell trafficking, cell motility, and survival. These receptors are activated by small molecular weight chemotactic cytokines called chemokines. Chemokine receptors play roles in the migration and localization of normal T cells (and other leukocytes) during physiological responses in inflamed or infected skin. In cancer cells, these receptors may also facilitate tumorigenesis, metastasis, and resistance to immune-mediated killing. This review will focus on recent data that reveal potential roles of specific chemokine receptors, including CCR4, CXCR4, and CCR10, in the pathophysiology of cutaneous T-cell lymphoma, including mycosis fungoides and Sézary syndrome.

Unlabelled: The tonsils have been identified as a site of replication for Epstein-Barr virus, adenovirus, human papillomavirus, and other respiratory viruses. Human tonsil epithelial cells (HTECs) are a heterogeneous group of actively differentiating cells. Here, we investigated the cellular features and susceptibility of differentiated HTECs to specific influenza viruses, including expression of avian-type and mammalian-type sialic acid (SA) receptors, viral replication dynamics, and the associated cytokine secretion profiles.

Antiretroviral therapy (ART) improves the quality of life for those living with the human immunodeficiency virus type one (HIV-1). However, poor compliance reduces ART effectiveness and leads to immune compromise, viral mutations, and disease co-morbidities. Here we develop a drug formulation in which a lipid-based nanoparticle (LBNP) carrying rilpivirine (RPV) is decorated with the C-C chemokine receptor type 5 (CCR5) targeting peptide.

Notably, the C-X-C Motif Chemokine Ligand 12/C-X-C Chemokine Receptor Type 4 (CXCL12/CXCR4) signalling pathway's activation is markedly increased in a mouse model of abdominal aortic aneurysms (AAA). Nonetheless, the precise contribution of this pathway to AAA development remains to be elucidated. The AAA mouse model was induced by local incubation with elastase and oral administration of β-aminopropionitrile.

CD8 T cells, a subset of T cells identified by the surface glycoprotein CD8, particularly those expressing the co-stimulatory molecule CD226, play a crucial role in the immune response to malignancies. However, their role in chronic lymphocytic leukemia (CLL), an immunosuppressive disease, has not yet been explored. We studied 64 CLL patients and 25 age- and sex-matched healthy controls (HCs).

Introduction: Challenges remain in reducing antigen escape and tumor recurrence while CAR-T cell therapy has substantially improved outcomes in the treatment of multiple myeloma. T cell receptor fusion construct (TRuC)-T cells, which utilize intact T cell receptor (TCR)-CD3 complex to eliminate tumor cells in a non-major histocompatibility complex (MHC)-restricted manner, represent a promising strategy. Moreover, interleukin-7 (IL-7) is known to enhance the proliferation and survival of T cells.
