1.
Kuntz T, Christensen R, Stegner J, Duff P, Koenig J
Pediatr Res . 2001 Dec; 50(6):743-9. PMID: 11726734
The Fas-Fas ligand (FasL) pathway of apoptosis is abnormally activated in diseases associated with impaired immune tolerance or chronic inflammation. Pregnancy-related hypertension is a spectrum of disease that commonly causes...

Koenig J, Luttge B, Benson N, Christensen R
Early Hum Dev . 2001 Oct; 65(2):159-63. PMID: 11641036
We used flow cytometric analysis to determine the cell cycle characteristics of human CD34+ cells from fetal bone marrow (BM), adult BM, and umbilical cord blood (UCB) samples. Fetal BM...

Koenig J, Chegini N
Am J Reprod Immunol . 2001 Feb; 44(6):347-9. PMID: 11200813
Problem: To determine if feto-placental tissues from gestations complicated by pregnancy-induced hypertension (PIH) have altered expression of Fas-associated proteins. Method Of Study: The expression of several Fas-related proteins was determined...

Koenig J, Baron S, Luo D, Benson N, Deisseroth A
Pediatr Res . 1999 Jun; 45(6):867-70. PMID: 10367780
L-selectin, a surface adhesion glycoprotein expressed on leukocytes, has a well-established role in mediating inflammation and lymphocyte recirculation. Recent evidence suggests that L-selectin may also influence hematopoiesis. We observed that...

Allgaier B, Shi M, Luo D, Koenig J
J Leukoc Biol . 1998 Sep; 64(3):331-6. PMID: 9738659
Apoptosis mediates neutrophil (PMN) phagocytosis and is influenced by cytokines and the Fas/Fas ligand pathway. To determine whether apoptosis of cord blood PMN differs from those of adults, cultured PMN...

Koenig J, Simon J, Anderson D, Smith E, Smith C
Pediatr Res . 1996 Apr; 39(4 Pt 1):616-21. PMID: 8848334
We have previously shown that surface levels of the adhesive glycoprotein, L-selectin, are diminished on cord blood neutrophils (polymorphonuclear leukocytes, PMN) and associated with impaired adherence to endothelium under flow...

Koenig J, Hunter D, Christensen R
J Perinatol . 1991 Dec; 11(4):355-8. PMID: 1770393
Neutropenia is common in neonates with sepsis and in those born to women with pregnancy-induced hypertension. Neutropenia has not previously been described, however, as a result of the twin-twin transfusion...

Christensen R, Liechty K, Koenig J, Schibler K, Ohls R
Blood . 1991 Sep; 78(5):1241-6. PMID: 1878592
Very high concentrations of erythropoietin (epo), in clonogenic cultures, result in reduced production of neutrophils, and fetal progenitors are more sensitive to this effect of epo than are those of...
9.
Koenig J, Christensen R
Am J Obstet Gynecol . 1991 Aug; 165(2):467-73. PMID: 1714678
The neonatal neutropenia after pregnancy-induced hypertension is a function of diminished neutrophil production. These studies test the hypothesis that this diminution is due to decreased production of neutrophilic growth factors,...

Koenig J, Chahine A, Ratnoff O
J Lab Clin Med . 1991 Jun; 117(6):523-7. PMID: 1646270
The initial step in the formation of thrombin via the intrinsic pathway is the activation of Hageman factor (factor XII). Some, but not all, studies have shown that this activation...
