Prolonged decrease
of adipocyte size after rosiglitazone treatment in high - and low - fat - fed rats.
The close relationship between adipocyte size and the abundance of macrophages in adipose tissue suggests that the influence
of adipocyte size on adipocyte function may be conveyed through a paracrine pathway involving adipose tissue macrophages.

This phenomenon is more frequent in obese patients, in whom the
size and number
of PPAT
adipocyte cells are higher.
The accumulation
of adipose tissue macrophages in direct proportion to
adipocyte size and body mass may explain the coordinated increase in expression
of genes encoding macrophage markers observed in our microarray expression data.
Our data in humans and mice show that
adipocyte size is a strong predictor
of the percentage
of macrophages in adipose tissue (Figure 3e).
These data demonstrate that variations in continuous quantitative traits such as body mass,
adipocyte size, and BMI are correlated with quantitative variations in the expression
of genes.
In subcutaneous and parametrial adipose tissue, the mean
adipocyte size of the FVB / NJ Csf1op / op mice (311 ± 71 μm2) was smaller though not significantly different from that
of control FVB / NJ Csf1 + / + mice (476 ± 326 μm2)(P = 0.37).
In mice, both body mass and
adipocyte size were strong predictors
of the percentage
of F4 / 80 + macrophages in the perigonadal, perirenal, mesenteric, and subcutaneous adipose tissue depots.
Immunohistochemical analysis
of perigonadal, perirenal, mesenteric, and subcutaneous adipose tissue revealed that the percentage
of cells expressing the macrophage marker F4 / 80 (F4 / 80 +) was significantly and positively correlated with both
adipocyte size and body mass.
Immunohistochemical analysis
of human subcutaneous adipose tissue showed that both BMI and
adipocyte size were strong predictors
of the percentage
of CD68 - expressing macrophages.
The researchers selectively ablated Lsd1 and inactivated its catalytic activity in brown
adipocytes, which triggered a profound whitening
of brown adipose tissue: The colour
of the brown fat cells became paler, their
size increased and they started to store energy instead
of expending it.
Overgrown tissue was composed
of normal -
sized, UCP1 - negative unilocular
adipocytes, with mitochondrial network fragmentation, disorganised cristae, and increased autophagosomes.

When you gain body fat, it's a combination
of growth in fat cell
size and the formation
of new
adipocytes (aka fat cells) through a process called adipogenesis, or
adipocyte differentiation [13].
