OBJECTIVE: To study the postnatal changes in lymphocyte subsets in early preterm infants and the effect of perinatal factors on lymphocyte subsets. METHODS: A total of 61 early preterm infants were enrolled. Flow cytometry was used to measure the absolute counts of lymphocytes and lymphocyte subsets at 1, 7, 14, and 28 days after birth, as well as at 6 months after birth for 17 of these early preterm infants. The effects of perinatal factors, such as antepartum use of hormone, intrauterine infection, gestational age at birth, and Ureaplasma urealyticum (UU) colonization, on lymphocyte subsets were analyzed...

Intestinal inflammation alters immune responses in the mucosa and destroys colon architecture, leading to serious diseases such as inflammatory bowel disease (IBD). Thus, regulation of inflammation is regarded as the ultimate therapy for intestinal disease. Substance-P (SP) is known to mediate proliferation, migration, and cellular senescence in a variety of cells. SP was found to mobilize stem cells from bone marrow to the site of injury and to suppress inflammatory responses by inducing regulatory T cells (Tregs) and M2 macrophages...

Parents-offspring bonding is critical for development of offspring in mammals. While it is known that pups stimuli provide rewarding effects on their parents, few studies have assessed whether parental stimuli serve as a reinforcing agent to their pups, and what the neural mechanisms underlying this reward process may be. In addition to maternal care, male ICR mice display pairmate-dependent parental behavior. Using the conditioned place preference (CPP) paradigm, we examined the effects of maternal and paternal conditioning on the postnatal day 17-21 female ICR mice pups, and compared the central expression of oxytocin (OT)- and tyrosine hydroxylase (TH)- immunoreactive (IR) neurons...

Bone and cartilage destruction is one of the key manifestations of rheumatoid arthritis (RA). Although the role of T helper (Th)17 cells in these processes is clear, the role of IL-21-producing cells T cells has been neglected. We sought to investigate the role of IL-21 in RA by focusing on the functional characteristics of the main producers of this cytokine, synovial CD4(+)IL-21(+) T cells. We show that the frequency of both synovial fluid (SF) CD4(+)IL-21(+) or CD4(+)IL-21(+)TNF(+) T cells in patients with RA was significantly higher compared with patients with psoriatic arthritis (PsA)...

TL1A contributes to the pathogenesis of several chronic inflammatory diseases, including those of the bowel by enhancing TH1, TH17, and TH2 responses. TL1A mediates a strong costimulation of these TH subsets, particularly of mucosal CCR9(+) T cells. However, the signaling pathways that TL1A induces in different TH subsets are incompletely understood. We investigated the function of TL1A on human TH17 cells. TL1A, together with TGF-β, IL-6, and IL-23, enhanced the secretion of IL-17 and IFN-γ from human CD4(+) memory T cells...

BACKGROUND: The survival of neonates who have been admitted to the NICU, especially premature infants with few mortality and morbidity, is the most important attitude. OBJECTIVES: We presumed whether urinary uric acid/creatinine (UUA/Cr) ratio can be a marker of mortality and adverse outcome in neonates which were admitted to the NICU. PATIENTS AND METHODS: All preterm infants admitted to our NICU after birth from March 2014 to April 2015 were enrolled in this prospective cohort study...

Fas and Fas Ligand (FasL) are two molecules involved in the regulation of cell death. Their interaction leads to apoptosis of thymocytes that fail to rearrange correctly their T cell receptor (TCR) genes and of those that recognize self-antigens, a process called negative selection; moreover, Fas-FasL interaction leads to activation-induced cell death, a form of apoptosis induced by repeated TCR stimulation, responsible for the peripheral deletion of activated T cells. Both control mechanisms are particularly relevant in the context of autoimmune diseases, such as multiple sclerosis (MS), where T cells exert an immune response against self-antigens...

INTRODUCTION: Total hip arthroplasty (THA) is a common surgery presenting well-known failures that may require surgical revision. To reduce the risk of hip dislocation after revision THA, we hypothesize the interest of the use of a new generation dual mobility cup by evaluating its survival and complication rates. MATERIALS AND METHODS: We analyzed the survival and the failures rate of 91 patients who underwent revision THAs with a specific dual mobility cup Novae® E TH (SERF, Décines-Charpieu, France)...

INTRODUCTION: In the pathogenesis of asthma, an imbalance between helper T (Th) 1/Th2 and Th17/Treg cells is believed to play a key role in asthmatic inflammatory responses. Some studies indicated that zinc deficiency increases inflammatory factor production and worsens asthma. However, the effects of zinc on T cell profiles to reduce inflammatory response remain unclear Objectives: We investigated the beneficial effects of zinc on isolated cell populations and cytokine levels from patients with asthma...

In 1974, warrior poet mother Audre Lorde published the poem "Blackstudies," a freeform dream villanelle about her complicated experience as a Black lesbian feminist English professor at the City University of New York during the dynamic period when students rose up in protest. The university granted open admissions, and cultural nationalists who taught at City University worked to create a Black Studies program. In the poem, she describes her vantage point at this particular historical and pedagogical moment from the seventeenth floor within a dreamscape where she navigates the stereotypes, silences, and urgencies that shaped her experience as an educator...

Th17 cells are a newly found subset of distinct CD4+ Th effector cells' family and are found to play an important role in cancers. Myelodysplastic syndromes (MDS) are a common malignant hematological disease. Here, we showed that both the percentage and the function of Th17 cells were elevated in low-risk MDS while being decreased in high-risk MDS. Levels of upstream molecules of Th17 cells, IL-6 and IL-23, were higher in low-risk MDS but lower in high-risk MDS patients. The abnormal percentage of Th17 cells was closely related to clinical parameters including karyotype, morphologic blast percentage of bone marrow, peripheral absolute neutrophil count, and hemoglobin concentration...

: This randomized clinical trial investigated the effectiveness of exercise vs. exercise plus trigger point dry needling (TrP-DN) in subacromial pain syndrome. A randomized parallel-group trial, with 1-year follow-up was conducted. Fifty subjects with subacromial pain syndrome were randomly allocated to receive exercise alone or exercise +TrP-DN. Participants in both groups were asked to perform an exercise program of the rotator cuff muscles twice daily for 5 weeks. Further, patients allocated to the exercise +TrP-DN group also received dry needling to active TrPs in the muscles reproducing shoulder symptoms during the 2(nd) and 4(th) sessions...

BACKGROUND: Iatrogenic parasitic myomas (PMs), caused by intra-corporeal power morcellation during laparoscopy is gradually increasing. However, the pathogenesis and medical treatment of PMs remain largely unelucidated. METHODS: Laparoscopically-induced PM xenografted mouse model was conducted by xenografting human uterine myoma fragments into the abdominal cavity of SCID mice and hormonal manipulation was performed using this mouse model to demonstrate the role of oestrogen in the development of implanted PMs...

Studies in experimental autoimmune encephalomyelitis (EAE), a murine model of multiple sclerosis (MS), have shown that regulatory B cells modulate the course of the disease via the production of suppressive cytokines. While data indicate a role for transforming growth factor (TGF)-β1 expression in regulatory B cell functions, this mechanism has not yet been tested in autoimmune neuroinflammation. Transgenic mice deficient for TGF-β1 expression in B cells (B-TGF-β1(-/-)) were tested in EAE induced by recombinant mouse myelin oligodendrocyte glycoprotein (rmMOG)...

Counter-balancing regulatory mechanisms, such as the induction of regulatory T cells (Treg), limit the effects of autoimmune attack in neuroinflammation. However, the role of dendritic cells (DCs) as the most powerful antigen-presenting cells, which are intriguing therapeutic targets in this context, is not fully understood. Here, we demonstrate that conditional ablation of DCs during the priming phase of myelin-specific T cells in experimental autoimmune encephalomyelitis (EAE) selectively aborts inducible Treg (iTreg) induction, whereas generation of T helper (Th)1/17 cells is unaltered...
