  Two-photon microscopy experiments demonstrated that most contacts between GC B and Tfh cells are of short duration (about 2 min), and only about 4% of these contacts lead to the formation of stable conjugates (5 to 60 min) (Allen et al., 2007). Similarly, during extrinsic peptide stimulation, some r

  While a number of studies have helped elucidate the principles of target amino group specificity, UBL selectivity, and Ub cfse specificity [3], [4], [9], [10], [14], [19], [20], [23], [24], [33], [34], [37], [38], [39], [40], [41], the role of the canonical E2-RING interface in governing substrate

  Despite the fact that the precise relevance of Ube2E self-ubiquitination in vivo is still elusive, findings of Sarkari et al. do establish Ube2E1 ubiquitination in s6 kinase [36]. In vivo self-ubiquitination of Ube2E1 is further supported by the high-throughput study aimed to identify all ubiquitin

  Due to the high attractiveness of E2 and E3 ligases as drug targets, a number of drug discovery assays have been published, based on detection by fluorescence (Dudgeon et al., 2010, Krist et al., 2016, Zhang et al., 2004), SB 290157 trifluoroacetate salt (Davydov et al., 2004, Huang et al., 2005, K

  2021-05-05

  

  Introduction Protein modification by ubiquitin and ubiquitin-like proteins is one of the most common and important regulatory mechanisms in biology (Finley et al., 2004, Pickart, 2004). Ubiquitination is carried out by an enzymatic cascade consisting of three steps. In the first step, ubiquitin i

  Although DAPK has been implicated in neuronal death in ischemic stroke and neurodegenerative diseases, such as Alzheimer’s disease (Shamloo et al., 2005, Duan et al., 2013), the mechanisms about how DAPK regulates cell death are still elusive. In the present study, we investigated the signal transdu

  These cytokines, except for TGF-β can also increase CysLT1R mRNA expression. We further demonstrated that TGF-β and IL-13 were able to increase the proliferation of human BSMC in response to LTD4. BSMC proliferation was CysLT1R-dependent, given that Montelukast ablated this effect. Taken together, o

  Some studies have demonstrated that BMSCs can provide several trophic and growth factors that play important roles in cell survival, angiogenesis, and BMSC differentiation, but not cell replacement (Peled et al., 1999, Shen et al., 2007, Ji et al., 2004). This paracrine effect of BMSCs is a potentia

  Since the aggregation of neurotoxic forms of Aβ plays a pivotal role in AD pathogenesis, an approach that using small molecules to bind Aβ monomers and prevent their assembly into cytotoxic oligomers attracts great interest for the development of AD drugs. Therefore, the potential inhibitory activit

  Introduction Breast cancer is the most common malignant tumor in women and the second leading cause of female death [1]. In recent years, with the improvement of early detection and the emergence of new treatment methods, the mortality rate of breast cancer has been greatly reduced. However, the

  Increased leukocyte trafficking and infiltration of the vascular wall are thought to provide a key stimulus for SMC activation and subsequent neointima formation in response to vascular injury [19], [20]. The essential trigger regulating the accumulation of leukocytes in the vessel wall is the upreg

  What are the molecular signals that guide Tfh cells as they navigate around the lymph node in the course of the immune response? It was recently reported that Tfh cells inside GCs have high expression of SIPR2, which acts to repel them from the S1P-rich lymph in the SCS and promote their retention i
