Volume reabsorption by the Loop of Henle: A micropuncture study

Experientia, 1980
The observed extension of glomerulo-tubular beyond the proximal tube is thought to be due either to flow dependent reabsorption by non-accessible proximal segments and pars recta, or to osmotic volume flow out of the descending limb of the loop of Henle.

Transport Characteristics of the Loop of Henle

1978
The loop of Henle was early identified as a structure essential for the concentration of the urine, since it occurs only in birds and mammals, the two classes that produce urine with osmolality higher than the blood. Subsequent study of the loop of Henle has mainly involved its role in urinary concentrating mechanisms.

Claudin Function in the Thick Ascending Limb of Henle's Loop

Annals of the New York Academy of Sciences, 2009
During the past decade, claudins have been established as major determinants of paracellular permeablilty in epithelia. In the kidney, each nephron segment expresses a distinct pattern of claudins. Cells of the thick ascending limb of Henle's loop (TAL), which is characterized by high paracellular cation permeability, co‐express an unusually large ...

Structure and Function of the Thin Limbs of the Loop of Henle

Comprehensive Physiology, 2012
Abstract The thin limbs of the loop of Henle, which comprise the intermediate segment, connect the proximal tubule to the distal tubule and lie entirely within the renal medulla. The descending thin limb consists of at least two or three morphologically and functionally distinct subsegments and participates in ...

Tubuloglomerular Feedback Signal Transduction in a Short Loop of Henle

Bulletin of Mathematical Biology, 2009
In previous studies, we used a mathematical model of the thick ascending limb (TAL) to investigate nonlinearities in the tubuloglomerular feedback (TGF) loop. That model does not represent other segments of the nephron, the water, and NaCl transport along which may impact fluid flow rate and NaCl transport along the TAL.

Indinavir Crystallization Around the Loop of Henle: Experimental Evidence

JAIDS Journal of Acquired Immune Deficiency Syndromes, 2001
To determine the probable site of the nephron and the plasma indinavir (IDV) concentration at which intrarenal IDV crystallization occurs.We performed in vitro crystallization experiments in IDV solutions simulating conditions found in the nephron.To determine intrarenal IDV concentrations at which conditions in the nephron allow crystallization ...

The thin limbs of Henle's loop in the rabbit

Cell and Tissue Research, 1980
The thin limbs of short and long loops of Henle of the rabbit kidney were studied by freeze fracture techniques. According to TEM studies of thin sections four segments are discernible: descending thin limbs of short loops, descending thin limbs of long loops, subdivided into an upper and a lower part, and ascending thin limbs (Kaissling and Kriz 1979).

The Loop of Henle, Distal Tubule and Collecting Duct

1994
The nephron segments beyond the proximal tubule are sometimes termed “the distal nephron”. In this chapter we will deal with the loop of Henle separately, and then consider the other components of the “distal nephron”.

Function of Thin Segments of Henle’s Loop

1991
It is well known that the renal medulla plays an important role in the generation of concentrated urine, which is critical in the maintenance of body fluid osmolality. Since the proposal of the operation of countercurrent systems in the renal medulla by Kuhn and his associates [1–3], it has been widely accepted that the loop structures of the nephron ...

Calcium Transport in the Pars Recta and the Loop of Henle

1980
Studies in isolated rabbit renal tubular segments perfused in vitro point to an important role for the proximal straight tubule and the thick ascending limb, but not the thin descending limb, in calcium transport.
