Study reveals how drug-seeking habits contribute to the perpetuation of addiction

Why are some individuals able to use recreational drugs in a controlled way, whereas others switch to the compulsive, relapsing drug-seeking and -taking habits that characterize substance use disorder (SUD)? Despite more than six decades of extensive research, the question remains unanswered, hampering the development of targeted prevention and therapeutic strategies.

Parietooccipital fissure contributes to the invasion pattern of posterior medial temporal gliomas

Researchers from four academic neurosurgical centers in Japan found that the parietooccipital fissure, which divides the temporal, occipital, and parietal lobes of the brain, acts as an obstacle that may result in less invasion of posterior medial temporal gliomas toward the occipital lobe.

SARS-CoV-2 protease suppresses host immune response by cleaving NEMO

A recent study conducted by a team of US-based scientists has highlighted a novel function of 3C-like protease of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The protease has been found to cleave a human immune signaling protein called NF-kB Essential Modulator (NEMO) and disrupt the host immune response.
