CC chemokines are a large subfamily of chemokines that play an important role in the innate immune system. To date, several CC chemokines have been identified in fish species; however, the activities and functions of these putative chemokines remain ambiguous in teleosts, especially in the golden pompano, Trachinotus ovatus. Here, we characterized CC chemokine ligand 4 from T. Read More

Apoptotic endonucleases act cooperatively to fragment DNA and ensure the irreversibility of apoptosis. However, very little is known regarding the potential regulatory links between endonucleases. Deoxyribonuclease 1 (DNase I) inactivation is caused by alternative splicing (AS) of DNase I pre-mRNA skipping exon 4, which occurs in response to EndoG overexpression in cells. Read More

Tumor-infiltrating lymphocytes are related to positive clinical prognoses in numerous cancer types. Programmed death ligand 1 (PD-L1), a mediator of the PD-1 receptor, plays an inhibitory role in cancer immune responses. PD-L1 upregulation can impede infiltrating T-cell functions in lung adenocarcinoma (LUAD), a lung cancer subtype. Read More

ARHGEF1 is a RhoA-specific guanine nucleotide exchange factor expressed in hematopoietic cells. We used whole-exome sequencing to identify compound heterozygous mutations in ARHGEF1, resulting in the loss of ARHGEF1 protein expression in two primary-antibody-deficient siblings presenting with recurrent severe respiratory tract infections and bronchiectasis. Both ARHGEF1-deficient patients showed an abnormal B cell immunophenotype, with a deficiency in marginal-zone and memory B cells and an increased frequency of transitional B cells. Read More

Background: HLA class I contributes to HIV immune control through antigen presentation to both cytotoxic T lymphocytes (CTLs) and natural killer (NK) cells. However, by contrast with investigations of CTL, studies of NK cells in HIV control through HLA-killer immunoglobulin-like receptor (KIR) interactions remain sparse in African cohorts.
Methods: 312 treatment naïve, chronically HIV-infected adults were recruited from South Africa, and the effects of HLA-KIR pairs on clinical outcome were statistically analyzed. Read More

Chronic lymphocytic leukemia (CLL) is the most frequent leukemia type in which the genetic alterations influencing the clinico-biological course are not entirely understood. CLL has a heterogeneous course, with some patients showing an indolent course, and others experiencing an aggressive course. Whole-genome sequencing (WGS) and whole-exome sequencing (WES) studies identified recurrently mutated genes in CLL, and profiled its clonal evolution patterns. Read More

Although Berberis plant species have been advocated as immune modulators, information regarding their mechanism(s) of action is limited. Therefore, in the present study we assessed the efficacy of Berberis lycium Royle fruit extract (BLFE) in the attenuation of lipopolysaccharide (LPS)-induced oxi-inflammatory aggravation and concanavalin A (Con-A)-induced proliferation in murine peritoneal macrophages and lymphocytes, respectively. BLFE strongly suppressed production of the oxidative and inflammatory effector molecules nitric oxide (NO), reactive oxygen species (ROS), inducible nitric oxide synthase (iNOS), inflammatory cytokines (TNF-α/IL-6/IL-1β/IFN-γ) as well as chemokines (MCP-1 and RANTES), with a concomitant enhancement in heme oxygenase-1 (HO-1) and IL-10 levels.

PD-1/PD-L1 checkpoint therapy for cancer is commonly considered to act by reactivating T cells in the tumor microenvironment. Here, we present data from 2 mouse tumor models demonstrating an essential involvement of tumor-draining lymph nodes in PD-1 and PD-L1 therapeutic efficacy. Immune activation induced by checkpoint treatment was predominantly observed in the tumor-draining, but not nondraining, lymph nodes and was reflected in local accumulation of CD8+ T cells. Read More

Chemokines are essential guidance cues orchestrating cell migration in health and disease. Cognate chemokine receptors sense chemokine gradients over short distances to coordinate directional cell locomotion. The chemokines CCL19 and CCL21 are essential for recruiting CCR7-expressing dendritic cells bearing pathogen-derived antigens and lymphocytes to lymph nodes, where the two cell types meet to launch an adaptive immune response against the invading pathogen.

Primary Sjögren's syndrome (pSS) is an autoimmune disease affecting the salivary and lachrymal glands. The patients complain of symptoms of dry eyes and dry mouth, but up to 50 % may additionally develop extraglandular manifestations such as arthritis, vasculitis, polyneuropathy, pulmonary fibrosis or interstitial nephritis. Most therapeutic studies on the glandular manifestations of pSS failed to meet their primary endpoints, possibly since many of the patients had already advanced and irreversible disease. Read More

Background: In a proportion of patients with chronic lymphocytic leukemia (CLL), resistance to Bruton tyrosine kinase (BTK) inhibitors (BTKi) is attributed to acquired BTK/phospholipase C gamma 2 (PLCG2) mutations. However, knowledge regarding additional genetic lesions associated with BTK/PLCG2 mutations, and gene mutations in patients lacking BTK/PLCG2 mutations, is limited.
Methods: Using targeted deep sequencing, mutations in 29 genes associated with CLL and/or the BCR signaling pathway were assessed in patients with CLL who developed resistance to BTK inhibition with ibrutinib/acalabrutinib at a single institution. Read More
