ClC-2 is a ubiquitously expressed plasma membrane Cl channel that reportedly controls the ionic environment in mouse retina and testis. Beyond that, ClC-2 might sense cellular energy status and cellular stress by its carboxyterminal cystathionine-beta-synthase (CBS) domains and by its molecular interaction with the heat shock protein Hsp90, respectively. In mature human and mouse erythrocytes, ...

Erythrocytes from blood of mice infected with Eperythrozoon coccoides for 3 or 4 days agglutinated spontaneously. Washed E. coccoides particles agglutinated washed erythrocytes of uninfected mice. E. coccoides-mediated agglutination of normal mouse erythrocytes would be an excellent system for studies of bacterial adhesion.

Development of the hematopoietic system proceeds in a multistep manner. Primitive erythrocytes are the first hematopoietic cells to be observed that were produced transiently in developing embryos. Multilineage lymphohematopoiesis occurs after the primitive erythropoiesis. However, the lineage relationship of cells that comprise embryonic hematopoietic system is not well characterized. To clari...

We show that mouse sperm die spontaneously within 1-2 days in culture and that treatment with either staurosporine (STS) and cycloheximide (CHX) or a peptide caspase inhibitor does not accelerate or delay the cell death. Chicken erythrocytes, by contrast, are induced to die by either serum deprivation or treatment with STS and CHX, and embryonic erythrocytes are more sensitive than adult erythr...

Heparin inhibited hemagglutination (HA) by equine arteritis virus (EAV) as well as did HA by Aujeszky's disease virus (ADV), but failed to inhibit HA by parainfluenza virus type 3 (PIV-3). The minimal concentration of heparin required to inhibit 8 HA U of EAV was 0.1 U/ml. In addition, most EAV hemagglutinin was retained by heparin acrylic beads, as was ADV hemagglutinin, but was not PIV-3 hema...

Background: Deoxygenation of sickle erythrocytes activates a cation permeability of unknown molecular identity (Psickle), leading to elevated intracellular [Ca] ([Ca]i) and subsequent activation of KCa 3.1. The resulting erythrocyte volume decrease elevates intracellular hemoglobin S (HbSS) concentration, accelerates deoxygenation-induced HbSS polymerization, and increases the likelihood of cel...

The F1 hybrids of NZB and several normal mouse strains are known to produce less anti-erythrocyte (Coombs) autoantibody and develop a milder hemolytic anemia than their NZB parents. We have found that serum from some (NZB x CBA)F1 mice agglutinated erythrocytes from certain Coombs-positive NZB mice, often in extremely high titer, whereas other (CBA x NZB)F1 sera agglutinated erythrocytes from d...

Mouse, rat, rabbit, hamster, cow, pig, sheep, guinea-pig, dog and human erythrocytes were studied. A 0.9% or stronger solution of sodium chloride completely prevented haemolysis; sheep and pig erythrocytes appeared the more fragile, while human and dog erythrocytes were not haemolized in concentrations of 0.4% or more. Haemolysis of human, rabbit, cow, hamster, guineapig, pig and sheep erythroc...

Murine sperm initiate fertilization by binding to the specialized extracellular matrix of their complementary eggs, known as the zona pellucida. On the basis of data reported in this study, mouse sperm also bind to rabbit erythrocytes with higher affinity than they do to murine eggs. This unusual interaction between a germ cell and a somatic cell ("sperm-somatic cell adhesion system") is also c...
