Introduction Temperature has immunomodulatory effects on innate immune cells: incubating monocytes at low temperatures for example increases pro-inflammatory responses after LPS-stimulation. The mechanisms mediating this effect are still unclear. The activity of several ion channels is sensitive to changes in temperature, leading to cytosolic calcium influx. Calcium is universally involved in c...

An ultrasensitive enzyme immunoassay (immune complex transfer enzyme immunoassay) of antibody immunoglobulin G (IgG) to human immunodeficiency virus type 1 (HIV-1) has been developed using recombinant HIV-1 reverse transcriptase (rRT) as antigen. However, some disadvantages were noted in the use of rRT as antigen: rRT was produced only with low efficiency in widely used strains of Escherichia c...

Autophagy has been shown to be involved in the pathophysiology of developmental seizure-induced brain damage. The present study aimed to examine whether E-64d, an autophagy inhibitor, was able to facilitate developmental seizure-induced hippocampal mossy fiber sprouting, in particular sprouting-associated zinc transporter signals. Recurrent seizures were induced by penicillin every other day in...

BACKGROUND CD8 T cells are thought to play an important role in protective immunity to tuberculosis. The major histocompatibility complex class I subtype HLA-A*0201 is one of the most prevalent class I alleles, with a frequency of over 30% in most populations. HLA-A*0201 transgenic, H-2D(b)/mouse beta2-microglobulin double-knockout mice (HHD) which express human HLA-A*0201 but no mouse class 1,...

cd8+ t cells are thought to play an important role in protective immunity to tuberculosis. the major histocompatibility complex class i subtype hla-a*0201 is one of the most prevalent class i alleles, with a frequency of over 30% in most populations. hla-a*0201 transgenic, h-2db/mouse beta2-microglobulin double-knockout mice (hhd) which express human hla-a*0201 but no mouse class i, was shown t...

Amino acid sequences homologous to 259KLVGKL (X)16KLLR284 of human immunodeficiency virus type 1 reverse transcriptase (HIV-1 RT) are conserved in several nucleotide polymerizing enzymes. This amino acid motif has been identified in the crystal structure model as an element of the enzyme's nucleic acid binding apparatus. It is part of the helix-turn-helix structure, alpha H-turn-alpha I, within...
