2021-03-19

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

Common features of TdT, pol μ and pol λ TdT, pol μ and pol λ remain in a closed conformation throughout their catalytic cycle, contrary to pol β [24•, 53, 54•]. One possible explanation for this observation is that they have traded fidelity (which requires open-to-closed transition) for a very ti

In angiotensin 1 to G468 and G469, which are buried (Fig. 7a), residues 470–476 are equivalent to the surface loop L12 present in the crystal structure of the LigI complex (Fig. 7b) [17]. The OBD of DNA ligases adopts at least two distinct orientations during the catalytic cycle. In the adenylation

Discussion The differences in the kinetic properties of L-AmDH and LeuDH presented herein reflect a different kinetic mechanism. When compared to its parent enzyme, L-AmDH displayed a different substrate binding order, lower affinity for the keto substrate, and stronger product inhibition. The tw

Expression of DDR1 in endothelial cells has been previously described in human corneal blood vessels, and more recently, in murine atherosclerotic plaques (Franco et al., 2008, Mohan et al., 2001). So far, there is a lack of evidence for DDR1 expression in endothelial cells in the mouse Picrotoxin

In summary, the loss of seven Cyp3a genes lead to sexual dimorphic changes during the eight weeks of high fat diet treatment with Cyp3a-null female mice showing a healthier acclimation to a high fat diet through decreased weight gain, higher adiponectin, lower B-OHB levels, and a better response to

Alvocidib (flavopiridol) is a piperidine-chromenone derivative (Fig. 6D) that is not FDA approved, but is in clinical trials for breast, endometrial, and several other cancers and hematological malignancies (Table 4) [[100], [101], [102], [103], [104]]. This drug targets CDK9 (IC50 = 3.2 nM) and CDK

It is noteworthy that epidemiological studies have demonstrated that some GAD patients have experienced anxiety symptoms in childhood and young adulthood, whereas others have developed their disorder at a later age (especially persons ≥ 50 years of age) (Hoehn-Saric et al., 1993; Le Roux et al., 200

Similarly, EGCG restored the mitochondrial energy shortfall in fibroblasts and lymphoblasts of the patients affected by Down syndrome, even so the mechanism of the effect was not clearly known (Valenti et al., 2013). EGCG also stimulated the mitochondrial biogenesis by activation of nuclear respirat

The majority of APC/C subunits form a giant scaffold, which was originally named the arc lamp, based on its shape when viewing APC/C from one side (Figure 1 and Box 1) [24]. The scaffold consists of two modules: the TPR lobe resembles the curved post and lamp, and the platform resembles the molar co

In the case of high-fidelity polymerases, we propose that water is used to achieve negative selection against nucleotide binding. With specialized DNA polymerases, we propose that nucleobase desolvation plays a different yet important role in allowing these enzymes to replicate damaged DNA. In this
