Bicarbonate in cystic fibrosis

Abstract: Apart from the devastating lung disease, abrogated bicarbonate transport also leads to many other organ dysfunctions, which are outlined in the present review.

“…Notably, inhibition of mucus synthesis by NFA also occurred in the absence of TMEM16A, suggesting contribution of additional members of the TMEM16 protein family. TMEM16A could contribute to mucus release by providing a secretory pathway for HCO 3 2 , which helps to unfold and solubilize mucus (7,38). We found only a weak HCO 3 2 permeability of TMEM16A in patch-clamp experiments at a cytosolic Ca 2+ concentration of 1 mM (Supplemental Fig.…”

“…Mucus hyperproduction causes airway obstruction, reduced mucociliary clearance, and chronic inflammation, the predominant problems in CF (3). In CF, mucus is particularly viscous and adhesive as a result of compromised Cl 2 and HCO 3 2 secretion caused by defective CF transmembrane conductance regulator (CFTR) channels (6,7).…”

“…La conductancia del canal varía entre 6 y 11 pS dependiendo del tipo de célula, la temperatura y la concentración de iones. La secreción de HCO 3 por CFTR es regulada de forma dinámica por la concentración extracelular de Cl - [5] . La proteína CFTR también es capaz de transportar otras moléculas como los aniones poliatómicos como el glutatión (␥-L-glutamil-L-cisteinglicina [GSH]), que es el antioxidante extracelular más abundante en los pulmones y está implicado en la protección celular contra las especies reactivas de oxígeno (ROS).…”

“…a Las mutaciones mostradas en negrita son detectadas por el equipo de detección neonatal en Francia (kit Elucigen). Las mutaciones de patogenicidad moderada o de amplio espectro se muestran en cursiva; c.350G>A (R117H) en cis de la variante c.1210-12T [5] (T5) se considera una mutación asociada a la mucoviscidosis; en cis de la variante de empalme normal T7, R117H ya no se considera una mutación asociada a la mucoviscidosis, sino a los trastornos relacionados con CFTR con baja penetrancia.…”

“…The CFTR protein migrates to the surface of cells that line the pancreatic duct, airways, gastrointestinal tract, biliary tract, part of the male reproductive tract and cells that are part of sweat glands (50,75,79). CFTR forms a pore or channel that allows ions, including chloride and bicarbonate, to move from one side of the cell membrane to the other (Figure 1) (58,83).…”
