Reproductive physiology for conservation breeding
|
|
Umapathy’s group characterized the reproductive behavior of mouse deer in captivity. This was important for conservation breeding of mouse deer. In the study, they found mouse deer shows the shortest post-partum estrus period, during which the female mouse deer shows estrus and mates within 4-6 hrs of delivery.

While analysing the hormone profiles, they discovered 16-androstenes sex pheromones (androstenone and androstanol) in mouse deer. They examined molecular characteristics of these pheromones, their synthesis pathway and functions in the mouse deer reproduction.

What happens to bacteria in cold?
|
|
Recent study from Manjula Reddy’s lab has found how the peptidoglycan (PG) layers (below the cell membranes) in bacterial cells change in response to cold. The PG layer is made of short peptide chains, inter-connected to each other. There are two kinds of cross-links, called the 4-3 and 3-3 crosslinks (shown as a and b respectively in the image). Upon a cold shock, the 3-3 crosslinks increase, which the researchers think make the cells more resilient towards cold.

How an immune response protein functions in cells
|
|
Effector immune cells, such as T cells and natural killer cells, protect us against infection or cell transformation. They detect abnormal changes at the surface of other cells using receptors. Some of these receptors are called inhibitory; they restrain cytotoxicity of natural killer cells by binding to ligands on healthy cells and signaling through phosphorylation of tyrosine amino acid in its cytosolic tail. Santosh Kumar’s group looked into the mechanism of phosphorylation of these tyrosines.
In their recent paper, they found that the process is regulated by electrostatic interaction between the receptor’s cytosolic tail with the plasma membrane despite the tail’s overall neutral charge. The unique mode of engagement with the plasma membrane, shown by the intrinsically disordered (ID) KIR tail, has several unusual features: i) it allows an electrically neutral region to interact electrostatically with the plasma membrane, ii) it does not induce helix formation in the ID region, and iii) it confers to the ID region intrinsic abilities of both binding to and unbinding from the plasma membrane. Our results, on how this unusual electrostatic interaction regulates signaling, advance understanding of immune responses by inhibitory receptors and the biology of protein ID regions.

Immunity and autophagy working together
|
|
Study from Santosh Chauhan's lab shows unique mechanism where the innate immune proteins and autophagy machinery are recruited together to the bacteria for defense as well as for maintaining immune homeostasis.

Back to the past - From somatic cells to stem cells
|
|
Stem cells are powerful - they can make any cell from the many hundred kinds that our bodies have. But did you know that our body cells can also be converted into stem cells in labs? Check out the recent article by Tanishqa Chaubal on how and why scientists are converting the normal body cells to stem cells.

Why do snakes not have limbs?
|
|
When we have limbs, why do some animals not have them? Did they never have them? Or did they lose it over the course of evolution? Can we also lose our limbs? Check out the latest India Asks Why podcast to know more.
