Both psoriasis and atopic dermatitis (AD) are not only associated with an impaired stratum corneum barrier, but also with abnormal expression of the tight junction (TJ) proteins. Because host defense peptides, including LL-37, are overexpressed in lesional psoriatic skin but are downregulated in lesional AD skin, we hypothesized that LL-37 might regulate the TJ function in keratinocytes. We dem...
Candida albicans is the major fungal pathogen of humans. Its adhesion to host-cell surfaces is the first critical step during mucosal infection. Antimicrobial peptides play important roles in the first line of mucosal immunity against C. albicans infection. LL-37 is the only member of the human cathelicidin antimicrobial peptide family and is commonly expressed in various tissues, including epi...
Background. In addition to depressed cardiac reserve, peripheral factors may contribute to limit maximal exercise capacity in patients with congestive heart failure (CHF). To investigate the role of reduced active skeletal muscle mass, peak oxygen uptake (Vo2, milligrams per kilogram per minute) was determined during maximal symptom-limited exercise involving the lower limbs (LL) alone and the ...
Let G be a multigraph of maximum degree Ll and with a set oft vertices of degree one, called terminals. We call G a (Ll, t)-network if for any pairing of its terminals there exist edge-disjoint paths in G between those pairs (tis even). The concept of (Ll, t)-networks is introduced to model the situation when switching processors having Ll ports are to be connected in such a way that simultaneo...
Human LL-37 is a multifunctional antimicrobial peptide that promotes inflammation, angiogenesis, wound healing, and tumor metastasis. Most effects of LL-37 are mediated via the activation of the cell surface G protein-coupled receptor FPR2 on leukocytes and endothelial cells. Although LL-37 induces chemotaxis, degranulation, and chemokine production in mast cells, the receptor involved and the ...
The human cathelicidin LL-37 has been shown to play a role in host defense against influenza A viruses (IAV) through direct antiviral effects and through modulating inflammatory responses to infection. We recently showed that LL-37 increases neutrophil respiratory burst and neutrophil extracellular trap (NET) responses to IAV through engaging formyl peptide receptor 2 (FPR-2). In this paper we ...
The human cathelicidin antimicrobial peptide LL-37 is involved in various aspects of skin biology, including protection against infection, wound healing, and also in psoriasis. The tight regulation of apoptosis is critical in tissue repair and its deregulation is a part of the psoriasis phenotype. Despite being involved in cell death of several cell types, virtually nothing is known about the f...
We investigated light acclimation in seedlings of the temperate oak Quercus petraea (Matt.) Liebl. and the co-occurring sub-Mediterranean oak Quercus pyrenaica Willd. Seedlings were raised in a greenhouse for 1 year in either 70 (HL) or 5.3% (LL) of ambient irradiance of full sunlight, and, in the following year, subsets of the LL-grown seedlings were transferred to HL either before leaf flushi...
PURPOSE To evaluate the potential utility of collagen-based corneal implants with anti-Herpes Simplex Virus (HSV)-1 activity achieved through sustained release of LL-37, from incorporated nanoparticles, as compared with cell-based delivery from model human corneal epithelial cells (HCECs) transfected to produce endogenous LL-37. METHODS We tested the ability of collagen-phosphorylcholine impl...
